Q)

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

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

So, $CH_3 CH_2CH_2COOH > CH_3CH_2CH_2CH_2OH > CH_3CH_2CH_2CHO$ (ie) $3 > 2 > 1$
