Most covalent compounds are poor conductors of electricity because they are:
AElectrically neutral
BElectrically charged
CAlways metallic solids
DAlways liquid at 25 C
Answer & Solution
Correct answer: A. Electrically neutral
1. Conduction needs mobile charge.
2. Whereas ionic compounds are good conductors of electricity when dissolved in water, most covalent compounds are insoluble in water.
3. Since they are electrically neutral, they are poor conductors of electricity in any state.
4. Neutral molecules supply no free ions to carry a current.
