Question

1. Which substance has dipole-dipole forces?

A.) CBr4 B.) SO3 C.)CHCl3 D.) F2

2. What kinds of intermolecular forces are present in a mixture of calcium bromide and water?

D.) dispersion and ion-dipole

3. Arrange the alcohols in order of decreasing surface tension.

Rank the alcohols from the strongest to weakest surface tension. To rank items as equivalent, overlap them.

A.) dipole-dipole and hydrogen bonding B.) dispersion, dipole-dipole, ion-dipole, and hydrogen bonding C.) ion-dipole

D.) dispersion and ion-dipole

3. Arrange the alcohols in order of decreasing surface tension.

Rank the alcohols from the strongest to weakest surface tension. To rank items as equivalent, overlap them.

CH CH CH,CH,OH

Answer:-

1. B.) SO3 ,

2. B.). dispersion, dipole-dipole, ion-dipole, and hydrogen bonding

3. As the molecular weight increases the suface tension of the alcohols decreases,

CH3CH2OH > CH3CH2CH2OH > CH3CH2CH2CH2OH > CH3CH2CH2CH2CH2OH
