Which solid conducts electricity most efficiently? (reasoning )
a. sodium chloride
b. sugar
c. graphite
d. gold

Option (c) is the correct answer.

Explanation:

Graphite is an allotrope of carbon and it is a solid which represents properties of both metals and non-metals.

It is known that in order to conduct electricity it is necessary for an atom or solution to have free or mobile electrons.

Graphite is a good conductor of electricity because of the presence of delocalised free electrons.

Thus, we can conclude that graphite is a solid which conducts electricity most efficiently.

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.
