Question

Which is not the property of a covalent compound?

• A. Crystalline hard solid
• B. Volatile
• C. Poor conductor of heat
• D. Soluble in organic solvents

Answer 1

The correct option is A

Crystalline hard solid

Part 1: Explanation for the correct answer -

Option a) Crystalline hard solid

• In covalent compounds, the force of attraction is very weak among the binding molecules.
• So, the covalent compounds are generally gases, liquids, or soft solids.

Part 2: Explanation for the incorrect answer-

Option b) Volatile

• Covalent compounds are highly volatile in nature as they have weak forces of attraction among the binding molecule and hence the intermolecular forces are very small due to which they are volatile.

Option c) Poor conductor of heat

• Covalent compounds are generally poor conductors of heat.

Option d) Soluble in organic solvents

• Covalent solvents are only soluble in organic solvents.

Hence, option (a) Crystalline hard solid is not a property of covalent compounds.
