Question

Quizplus · Accepted Answer

Isobutylamine has a branched chain of 2 carbon atoms and 1 methyl group on the second carbon, so the name consists of "2-methyl" to reflect this and "1-propanamine" to reflect the primary amine functional group. A and C are incorrect because they do not reflect the branching of the carbon chain, and D is incorrect because it suggests the presence of two methyl groups, which is not the case.
