Which of these is a typical property of a substance that is composed of atoms that are held together by covalent bonds?
it conducts electricity when in solid form.
it conducts electricity when in molten form.
it conducts electricity when it is dissolved in water.
it does not conduct electricity in any form.

The last choice.

Explanation:

It does not conduct electricity in any form.

They have no free electrons and do not ionise.

Option (d) is the correct answer.

Explanation:

A covalent bond is formed by sharing of electrons between two chemically combining atoms.

A covalent bond always forms between non-metals. And, for conduction of electricity we need ions or free flow of electrons.

But in a covalent bonds there is no availability of free electrons as electrons are being shared in a covalent bond. Also, they are unable to dissociate into ions.

As a result, covalent compounds are not able to conduct electricity in any form.

Thus, we can conclude that out of the given options it does not conduct electricity in any form is a typical property of a substance that is composed of atoms that are held together by covalent bonds.
