state reasons to explain why covalent compounds:
(i) are bad conductors of electricity?
(ii) have low melting and boiling points?
Answers
Explanation:
(i) Covalent compounds are bad conductors of electricity because they are formed by sharing of electrons. So they don't have any free electron that is required for carrying electricity. Thus they are bad conductors of electricity.
(ii) CovaLent compounds are formed by the sharing of electrons, hence the intermolecular forces are relatively weaker than the electrostatic forces existing between the ionic compounds that are formed by the transferring of electrons. Due to the weak intermolecular forces, less energy is needed to break the covalent bonds hence they have low melting and boiling points
Answer:
(i) because covalent bonds are formed by sharing of electrons..they don't have a free electron that is required for electricity transfer(electricity is the flow of free electrons!) thus they re bad conductors.. but ionic compounds are good conductor because of the same reason...
(ii) the picture is above
