Question

When two ice cubes are pressed over each other, they unite to form one cube. Which of the following forces is responsible to hold them together ?
(a) Hydrogen bond formation
(b) van der Waals forces
(c) Covalent attraction
(d) Ionic interaction

Answer 1

I think d is correct

Answer 2

Answer:(a) Hydrogen bond formation is the correct answer.

Explanation:

1) hydrogen bond formation:

The electrostatic force of attraction between positively charged hydrogen atom of one molecule and negatively charged atom of other molecule is called hydrogen bond.

There is dipole dipole attraction in hydrogen bond.

Ice molecules stick to each other and form hydrogen bond.

2) van der waal forces

Van der waal forces are intermolecular forces between two molecules. There are two types

1. Dipole dipole forces

2. London forces.

3) covalent attraction

Covalent bond is formed between shared pair of electrons. They are more stable.

Example HCl

4) ionic bond

Ionic bond involves complete transfer of electrons.
