Question

What is the name of this compound?

ethanal
ethylamine
ethanoic acid
methyl ethanoate

Answer 1

This molecule is ethylamine. The parent carbon chain is an eth- chain (because it has two carbons) and there is an amine group attached (-NH2) so it's ethylamine.

Answer 2

Answer: ethylamine

Explanation: The given compound contains a -
`NH_2` functional group which represents amines.

Also the compound contains two carbon atoms and thus the word root is -eth. As one of the hydrogen from ethane
`C_2H_6` is missing, the name changes to ethyl
`C_2H_5`.

The naming starts with the longest carbon chain and ends with the functional group.

Thus the name is ethylamine.

-al is used for aldehydes. -oic acid is used for carboxylic acids and -oate is used for esters.
