Question

An amine with two or more alkyl groups does not have a lone pair of electron on nitrogen atom.

(a) True

(b) False

I had been asked this question during an interview for a job.

Asked question is from Structure of Amines topic in section Amines of Chemistry – Class 12

Answer 1

Right option is (b) False

Explanation: Amines are derivatives of ammonia. Nitrogen of NH3 is sp^3 hybridised with one orbital having unshared pairs of electrons as it bonds to only three H atoms. Similarly, amines also have an electron lone pair on nitrogen.
