Model Answer

In covalent bonding, electrons are shared between atoms rather than transferred. Since no charged particles (ions) or free electrons are produced, carbon compounds cannot conduct electricity.

Source: Chapter 4, Section 4.1 – Bonding in Carbon

Explanation

The key phrase from the textbook is: "Since the electrons are shared between atoms and no charged particles are formed, such covalent compounds are generally poor conductors of electricity." For 1 mark, you only need to state that sharing (not transfer) of electrons means no free ions/electrons are available to carry charge.
