a. Aminopropane
b. Propanamine
c. both a and b
d. None of these

Answer 1

The IUPAC name of above compound is propanamine.

Answer 2

Answer: Option (b) is the correct answer.

Explanation:

Since functional group is present on the right side, therefore, numbering will start from the carbon adjacent to $NH_{2}$ group, that is, amine group.

Also, there are only three carbon atoms. Hence, the name of alkane comes first and then name of functional group will be added.

Therefore, IUPAC name of the compound $CH_{3}CH_{2}CH_{2}NH_{2}$ is propanamine.
