What intermolecular forces can be found in a molecule of ethene?

Possible Answers:

London dispersion forces and hydrogen bonding

London dispersion forces and dipole-dipole attraction

London dispersion forces just

London dispersion forces, hydrogen bonding, and dipole-dipole attraction

Dipole-dipole allure and ionic bonding

Correct answer:

London dispersion forces only

Explanation:

Ethene is an organic molecule equanimous of two carbon atoms, joined past a double bond, and iv hydrogen atoms.

H_2C=CH_2

Ethene, like all molecules, exhibits London dispersion forces. This molecule, however, has no net dipole moment, so it volition not exhibit dipole-dipole attraction. Likewise, even though it contains hydrogens, it does not exhibit hydrogen bonding. To showroom hydrogen bonding, the hydrogen atoms must be fastened to more electronegative atoms, namely nitrogen, fluorine, or oxygen. Finally, ionic bonding is only nowadays in ionic compounds, not organic compounds.

Which of the following has the highest boiling point?

Correct answer:

NaCl

Explanation:

Ionic bonds are the strongest blazon of bonds, followed by covalent bonds, hydrogen bonds, and lastly, van Der waals forces.

Which of the following substances has a higher boiling betoken?

Dipropyl Ether

Propanol

Possible Answers:

You must know the organisation temperature in order to determine the answer

They have equal boiling points

You must know the system pressure in guild to determine the respond

Dipropyl ether

Propanol

Explanation:

Although the two molecules seem similar in structure, proponol has a higher boiling point due to the hydrogen bonding allowed by its alcohol group. This creates a potent intermolecular force, and extra free energy is subsequently needed to break these bonds, resulting in a higher boiling point.

System pressure and temperature are related to boiling point, but are non necessary when comparing the properties of 2 molecules.

Which of the following is the strongest intermolecular force?

Possible Answers:

van Der Waals

Ion-dipole forces

Dipole-dipole forces

Covalent bonds

Ionic bonds

Right answer:

Ion-dipole forces

Explanation:

Ionic and covalent bonds are non intermolecular forces;

Ion-dipole>hydrogen bonds>dipole-dipole>van Der Waals forces

What is the strongest intermolecular strength in the following chemical compound?

CH_threeCH_twoCH₂CH₂OH

Possible Answers:

ionic bond

Hydrogen bail

covalent bail

van Der Waals

None of these

Correct answer:

Hydrogen bail

Explanation:

This is butanol. It is an booze; OH is the prime instance of hydrogen bonding, which is the strongest intermolecular force.

Which of the following intermolecular forces is the strongest?

Possible Answers:

Ionic bonds

Ion-dipole forces

Van der Waals forces

Dipole-dipole forces

Hydrogen bonds

Correct respond:

Ion-dipole forces

Explanation:

Ion-dipole forces are the strongest of the intermolecular forces.

Hydrogen bonding is a specific term for a specially strong dipole-dipole interaction between a hydrogen cantlet and a very electronegative atom (oxygen, fluorine, or nitrogen). However, hydrogen bonds are however not as strong every bit ion-dipole interactions.

In lodge from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces.

Ionic bonding is stronger than whatever of the given intermolecular forces, but is itself NOT an intermolecular strength. Ionic bonds are a permanent chemical connectedness between two atoms, whereas intermolecular forces equally a more transient and temporary attraction betwixt independent molecules.

Formaldehyde (H_2CO) has which of the following types of intermolecular forces?

Possible Answers:

London dispersion forces only

London dispersion forces, dipole-dipole attraction, and hydrogen bonding

London dispersion forces and dipole-dipole allure

Hydrogen bonding and dipole-dipole attraction

Dipole-dipole attraction only

Correct respond:

London dispersion forces and dipole-dipole attraction

Caption:

Formaldehyde, similar all atoms and molecules, will have very weak London dispersion forces created as electrons shift within the electron cloud. Because it possesses a permanent dipole (based on the polarized carbon-oxygen bond), formaldehyde also exhibits dipole-dipole interactions. Information technology does not, however, exhibit hydrogen bonding, because no hydrogens are attached to oxygen (or other electronegative atoms similar nitrogen or fluorine).

Select the selection that lists only intermolecular forces.

Possible Answers:

Hydrogen bonding and van der Waals forces

Metal bonding and covalent bonding

van der Waals forces and metallic bonding

Hydrogen bonding and metal bonding

Covalent bonding and ionic bonding

Correct respond:

Hydrogen bonding and van der Waals forces

Explanation:

There is a key difference between atomic bonds and intermolecular forces. Metallic bonds, ionic bonds, and covalent bonds are all atomic bonds. This means that they are generally stable and relatively irreversible. An diminutive bond volition modify the identity of a compound by adding an atom to the structure.

Intermolecular forces, in dissimilarity, are more transient and less stable. These attractions are constantly broken and reformed as molecules move around. Hydrogen bonds, dipole-dipole interactions, and van der Waals forces (London dispersion forces) are some common examples of intermolecular forces. Intermolecular forces volition never alter the identity of the molecule and cannot be used to add atoms to a compound.

Which of these is the strongest intermolecular force?

Possible Answers:

Ionic bonds

Covalent bonds

van der Waals forces

Dipole-dipole interactions

Hydrogen bonds

Right answer:

Hydrogen bonds

Explanation:

At that place is a key difference between diminutive bonds and intermolecular forces. Ionic bonds and covalent bonds are atomic bonds, pregnant they are intramolecular. This means that they are mostly stable and relatively irreversible. An atomic bond volition modify the identity of a chemical compound by adding an atom to the structure.

Intermolecular forces, in contrast, are more transient and less stable. These attractions are constantly cleaved and reformed as molecules move around. Hydrogen bonds, dipole-dipole interactions, and van der Waals forces (London dispersion forces) are some common examples of intermolecular forces. Intermolecular forces will never change the identity of the molecule and cannot be used to add atoms to a chemical compound.

The strongest intermolecular force is hydrogen bonding, which is a item subset of dipole-dipole interactions that occur when a hydrogen is in shut proximity (bound to) a highly electronegative chemical element (namely oxygen, nitrogen, or fluorine). The hydrogen takes on a partial positive charge and the electronegative atoms takes on a partial negative charge.

Lodge the following compounds by strength of their intermolecular forces, from weakest to strongest:

I. $H_{2}O$

II. $CH_{4}$

Three. $C_{2}H_{6}$

IV. {HBr}

V. NaCl

Possible Answers:

IV < Five < I < II < Iii

V < I < IV < Three < Ii

Ii < III < IV < I < 5

II < Three < I < IV < V

I < Two < 4 < V < Three

Correct respond:

2 < III < IV < I < Five

Explanation:

This is a question about intermolecular forces, or IMFs. In that location are four broad categories of IMFs, all of which are represented hither.

Since the question asks us to order the compounds from least strength to greatest, we'll start with the weakest International monetary fund: Van der Waals forces, too called "induced dipoles" or London dispersion forces.

Not-polar molecules like $CH_{4}$ and $C_{2}H_{6}$ can still exhibit temporary dipoles by consecration, when the electrons of one molecule push away the electrons of some other. In general, the more than electrons that are bachelor to push, the more potential there is for a dipole to occur. Therefore, $CH_{4}$ is weaker, because it has less electrons available than $C_{2}H_{6}$ .

The adjacent tier of IMF is permanent dipole interactions (dipole-dipole interactions) that are not hydrogen bonds. {HBr} is a polar molecule and experiences dipole interactions, which makes it the adjacent strongest in our list.

Next is hydrogen bonding, an especially powerful form of dipole interactions when hydrogen is bonded to a fluorine, oxygen, or nitrogen atom. $H_{2}O$ experiences hydrogen bonding because information technology has hydrogen atoms bonded to oxygen atoms. Because hydrogen bonds are a stronger course of dipole interactions, this puts $H_{2}O$ next in the list.

The strongest grade of intermolecular forcefulness is ionic forces, which exist in ionic compounds similar NaCl . So, NaCl exhibits the strongest IMFs.

Our final social club is CH_4 < C_2H_6 < HBr < H_2O < NaCl , or Ii < Iii < IV < I < Five.
