Answer : The name of the compound [tex]CH_3-CH_2-CH_2-NH_2[/tex] is, propylamine
Explanation :
The rules for naming the amines [tex](RNH_2)[/tex] :
- The selected longest continuous chain of carbon atoms must include [tex]-NH_2[/tex] 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 [tex]CH_3-CH_2-CH_2-NH_2[/tex] is, propylamine
