Question

Give a reason for the following:
Carbon tetrachloride is a liquid but does not conduct electricity.

Answer 1

Carbon tetrachloride ( $CCl_4$ ) is a chemical compound having the formula $CCl_4$ . It's a colourless liquid with a faintly pleasant odour that may be perceived at low concentrations. At lower temperatures, it is nearly inflammable. It was previously widely employed in fire extinguishers, as a forerunner to refrigerants, and as a cleaning agent, but due to environmental and safety issues, it has since been phased out. The central nervous system can be affected by large amounts of carbon tetrachloride (including vapour), and the liver and kidneys can deteriorate. Long-term exposure can be deadly.

Complete answer:
Non-polar covalent compounds are covalent compounds that have no variation in electronegativity. There is no change in electronegativity in these compounds, thus bond pairs of electrons do not move towards the linked atoms. As a result, no bond or dipole moment exists between the atoms of a molecule, and no charges build on the atoms, making the molecule non-polar and non-conducting. Polarity is absent in nonpolar substances. In a solution, they will not convert to ions. Nonpolar substances do not readily dissolve in water, which is a polar molecule, due to these characteristics. Because there are no charged particles in these materials, they are insulators. Because there is no ionisation between the particles, no charge-carrying ions, they are classified as insulators.
Non-conductive non-polar non-metal compounds are usually non-polar non-metal substances. Ionic solutions are generally exceedingly conductive because they are very polar and include charged atoms and molecules. Pure water is extremely polar, however it is a poor conductor due to the lack of charge mobility.

Note:
A nonpolar covalent link is a sort of chemical connection that occurs when two atoms share electrons evenly. As a result, the number of electrons shared by neighbouring atoms in an atom will be the same. Because the difference in electronegativity is usually small, the covalent bond is sometimes referred to as nonpolar. It also indicates that there is no charge difference between the two atoms or that their electronegativity is identical. When atoms that share a polar connection organise themselves in such a way that their electric charges cancel each other out, this sort of bond is produced.
