Identify the correct order of boiling points of the following compounds : $CH_3 CH_2 CH_2OH,CH_3CH_{\large 2_2}CH_2CHO , CH_3CH_{\large 2_3}CH_2COOH$

$(a)\; 1 > 2 > 3 \\ (b)\; 3 > 1 > 2 \\ (c)\; 1 > 3 > 2 \\ (d)\; 3 > 2 > 1 $

Can you answer this question?

Higher the molecular weight will be the boiling points.
So, $ CH_3 CH_2CH_2COOH > CH_3CH_2CH_2CH_2OH > CH_3CH_2CH_2CHO $ (ie) $3 > 2 > 1$
Carboxylic acid shows strongest inter molecular H- bonding and aldehyde shows weakest H-bond.
Hence d is the correct answer.
