Question

How many primary amines are possible for molecular formula C₃H₉N?

Options

• 4

• 1

• 2

• 3

Answer 1

2

Explanation:

Amine with molecular formula C₃H₉N have two primary structures. These are as follows:

1. \[\ce{\underset{\text{Propan-1-amlne}}{CH3CH2CH2NH2}}\]
2. \[\begin{array}{cc}
   \ce{CH3}\\
   |\phantom{...}\\
   \ce{\underset{\text{Propan-2-amlne}}{CH3 - CH - NH2}}\end{array}\]

Other isomers are not primary amines.
