Question

What is the correct match in the given options?

• A. Covalent bond - solid, Ionic bond - all three states
• B. Covalent bond - all three states, Ionic bond - solid
• C. Covalent bond - all three states, Ionic bond - liquid
• D. Covalent bond - solid, Ionic bond - all three states

Answer 1

The correct option is B

Covalent bond - all three states, Ionic bond - solid

Covalent compounds have shared a pair of electrons, which results in weak intermolecular forces that allows them to exist as gas or liquid or soft solids at room temperature.

Ionic bonds are usually formed due to the force of attraction between oppositely charged ions. Due to the strong intermolecular forces, they are held very tight and usually exist as solids.

For example - $NaCl$ is an ionic salt that exists in the solid state in room temperature, $H_{2}O$ is a covalent compound that is usually found in the liquid state and $HCl$ is found in the gaseous state in the room temperature.
