What is the predominant intermolecular force in the liquid state of each of these

Water- hydrogen bonding

Carbon tetraflouride- dispersion forces

Dichloromethane- dispersion forces

Explanation:

Hydrogen bonding exists when hydrogen is bonded to an electronegative element. This results in a permanent dipole in the molecule. However, nonpolar molecules such as dichloromethane are held only by the weak dispersion forces.

Land breeze is the wind that blows cool air from land towards sea at night.

Explanation:

Land breeze is a type of wind which is cool and blows towards sea. It occurs due to the difference in the temperature of water and land. At night, the lands cool quickly due to the removal of heat from it. So the air that is present on land is cool down and this air moves towards sea. So this breez is called land breeze because it moves from land.
