How many primary amine isomeric forms are possible for the formula C ₄ H ₁₁ N ?

Step-by-step solution

The general formula for a primary amine is R-NH ₂ . For the molecular formula C ₄ H ₁₁ N , the alkyl group R is the butyl group, C ₄ H ₉- . The butyl group has four structural isomers, which lead to four primary amines: 1. n-butylamine (Butan-1-amine): CH ₃ CH ₂ CH ₂ CH ₂ -NH ₂ 2. sec-butylamine (Butan-2-amine): CH ₃ CH ₂ CH ( NH ₂) CH ₃ 3. isobutylamine (2-Methylpropan-1-amine): ( CH ₃)₂ CHCH ₂ -NH ₂ 4. tert-butylamine (2-Methylpropan-2-amine): ( CH ₃)₃ C-NH ₂ Thus, there are 4 primary amine isomeric forms possibl
