CH3--CH2--C--COOH
||
CH2​

Answer 1

Answer:

number of carbon atoms in the principle carbon chain in the given compound are: 5

CH3--CH2--C--COOH

||

CH2

Explanation:

The number of carbon atoms in the principal chain of the given compound is five because the aldehyde group (here act as a substituent) and double bond has to be given the lowest number. Therefore, the numbering will start from the COOH group and ends in CH3 which will include a CHO group also.
