Always try to draw the structure it always helps.
Hope this helps :).

Answer 2

Answer : The name of the compound
`CH_3-CH_2-CH_2-NH_2` is, propylamine

Explanation :

The rules for naming the amines
`(RNH_2)` :

• The selected longest continuous chain of carbon atoms must include
  `-NH_2` group.
• The amines are named by suffixing -amine in palce of -e of the corresponding alkane.
• The carbon bearing the amine group gets the lowest possible numbering.
• In case of secondary amine, the longest chain is selected as a parent chain. The other alkyl group is named as prefix and written as N-alkyl before the parent chain. Thus, they are named N-alkylalkanamines.
• In case of tertiary amine, the longest chain is selected as a parent chain. The other two alkyl group is named as prefix and written as N,N-dialkyl before the parent chain.

In the given compound, the longest chain of carbon number is, 3 and the 3 carbon chain name is, propyl. First, write the name of the longest chain of carbon and then the functional group that is amine as a suffix.

Hence, the name of the compound
`CH_3-CH_2-CH_2-NH_2` is, propylamine
