Question

Which of the following physical properties are true regarding alkanes?

• A. exhibit a blue colour as a liquid.
• B. highly polar molecules.
• C. are non reactive species.
• D. have a very high boiling points.

Answer 1

The correct option is C are non reactive species.

A. Most of the members of alkanes are colorless.

B. They are highly nonpolar molecules as they contain only carbon and hydrogen atoms which are not having much difference in their electronegativities.

C. They do not contain any functional group and hence are nonreactive in nature.

D. Most of the members of alkane family are volatile in nature.

Hence, option $C$ is correct.
