उत्तर
Isobutylamine is an example of 1° amine.
Explanation:
The general formula for isobutylamine is \[\ce{(CH3)2−CH−CH2−NH2}\]. It is an ammonia derivative where the ammonia's solitary hydrogen atom is replaced with an isobutyl group. Therefore, in addition to the two \[\ce{N – H}\] bonds that are present and belong to a primary amine, isobutylamine also contains a secondary carbon atom.
