Here's how we can determine this:
* Understanding amines: Amines are organic compounds containing a nitrogen atom bonded to one or more alkyl groups (hydrocarbon chains).
* Possible structures: With C3H9N, the nitrogen atom must be bonded to three hydrogen atoms to satisfy its valency. This leaves three carbon atoms to be arranged. We can have:
* A primary amine: The nitrogen is bonded to one carbon chain (propyl amine).
* A secondary amine: The nitrogen is bonded to two carbon chains (isopropyl amine).
The two possible amines are:
1. Propyl amine (CH3CH2CH2NH2) - primary amine
2. Isopropyl amine (CH3CH(NH2)CH3) - secondary amine
