(d) Quaternary

The question was asked in an online interview.

I want to ask this question from Amines Classification topic in portion Amines of Chemistry – Class 12

Answer 1

Correct choice is (d) Quaternary

To elaborate: Amines may be classified as primary, secondary or tertiary depending on whether 1, 2 or 3 hydrogen atoms of NH3 are replaced by alkyl/aryl groups respectively. Quaternary ammonium compounds are a different class of compounds where all four hydrogen atoms of ammonium salts are replaced by alkyl/aryl groups.
