Identify tertiary amine from following.

Step-by-step solution

Tertiary amines are characterized by a nitrogen atom bonded to three alkyl or aryl groups, with no hydrogen substituents. Cyclohexanamine ( C ₆ H ₁₁ NH ₂ ) contains nitrogen bonded to one cyclohexyl group and two hydrogen atoms, making it a primary amine. Ethane 1,2-diamine ( H ₂ N - CH ₂- CH ₂- NH ₂ ) contains two nitrogen atoms, each bonded to an alkyl fragment and two hydrogens, classifying it as a primary diamine. N-Phenylbenzeneamine ( ( C ₆ H ₅)₂ NH ) contains nitrogen bonded to two phenyl groups and one hydr
