Question

Covalent compounds have low melting point because –

• A. Covalent molecules are held by weak Vander Waal’s forces
• B. Covalent bond is less exothermic
• C. Covalent bond is weaker than ionic bond
• D. Covalent molecules have definite shape

Answer 1

The correct option is A Covalent molecules are held by weak Vander Waal’s forces

The weaker Vander Waal’s forces present in covalent molecules compared to ionic molecules is responsible for low melting point of covalent compounds.
