Question

Boiling point order for butanol , butanal , butanoic acid

Answer 1

$Boiling \:points depends\: on \:strength\: of\: intermolecular \:interaction.\\ In \:case\: of \:butanol\: and butanoic acid \:there \:is\: H \:bonding\\ which \:is \:a \:stronger\: intermolecular \:attractive \:force.\\ Further \:butanoic \:acid \:remain\: in\: dimeric \:form\\ so \:there\: is\: more \:extent \:of \:H \:bonding. \\So\: order\: of \:boiling\: point \:is \\\\ butanoic \:acid > butanol > butanal$

Answer 2

Butanoic acid > Butanol > Butanal
