• A. Low melting and boiling points
• B. Soft or brittle solid forms.
• C. Good electrical and thermal conductivity.
• D. Poor electrical and thermal conductivity.

Answer 1

Answer: (A), (B), (D)

The correct options are
A

Low melting and boiling points

B

Soft or brittle solid forms.

D

Poor electrical and thermal conductivity.

Covalent compounds have -
Low melting points and boiling points.
Low enthalpies of fusion and vaporization These properties are usually one or two orders of magnitude smaller than they are for ionic compounds.
Soft or brittle solid forms.
Poor electrical and thermal conductivity.
