Explanation / Answer

Hi

1. There is no possibilty for hydrogen bonding, also no dipole forces are present. The only intermolecular forces present in molecule are dispersion forces.

2. HBr will be least soluble in water, since it cannot have hydrogen bonding.

3. Covalent substance never conduct electricity, neither in solid nor in liquid state. (Graphite is an exception.)

4. Water has the highest heat of vaporization, since hydrogen bonding is present between the molecules of water.

Thank you
