It has exactly 4 structural isomers that are primary amines. B. It has exactly 3 structural isomers that are secondary amines. C. Its primary, secondary, and tertiary amine isomers are considered functional isomers of each other. D. None of its isomers exhibit optical is

Step-by-step solution

For the molecular formula C₄H₁₁N : Statement A: The primary ( 1^ ) amines are butan-1-amine, butan-2-amine, 2-methylpropan-1-amine, and 2-methylpropan-2-amine. There are exactly 4 structural isomers. (True) Statement B: The secondary ( 2^ ) amines are N-methylpropan-1-amine, N-methylpropan-2-amine, and N-ethylethanamine. There are exactly 3 structural isomers. (True) Statement C: Primary, secondary, and tertiary amines have different functional groups ( -NH₂ , -NH- , and -N Statement D: Butan-2-amine ( CH₃CH(NH₂)CH
