Question

The intermolecular forces are maximum in case of:

• A. copper
• B. water
• C. glycerine

Answer 1

The correct option is A

copper

The explanation for the correct option:

(a) Intermolecular forces of attraction are maximum in solids, moderate in liquid, and weakest in gases. Since copper is a metal, hence it is solid and has high intermolecular force.

The explanation for the incorrect options:

(b) Water is a liquid, hence the intermolecular force of attraction will be weaker than copper.

(c) Glycerine is also a liquid but it is denser than water. Hence the intermolecular attraction will be greater than water but still less than copper.

Hence, option (a) that is copper is correct, as it is solid.
