The correct B.P. order of \(\mathrm{RCOOH}, \mathrm{ROH}\), \(\mathrm{RCHO}\) of same molar mass is
1 \(\mathrm{RCOOH}>\mathrm{RCHO}>\mathrm{ROH}\)
2 \(\mathrm{RCOOH}>\mathrm{ROH}>\mathrm{RCHO}\)
3 \(\mathrm{RCHO}>\mathrm{RCOOH}>\mathrm{ROH}\)
4 \(\mathrm{RCHO}>\mathrm{ROH}>\mathrm{RCOOH}\)
Explanation:
As acids have much more extent of \(\mathrm{H}\)-bonding, they posses highest \({\rm{B}} \cdot {\rm{P}} \cdot \) than alcohol. Alcohol posses high \({\rm{B}} \cdot {\rm{P}} \cdot \) than aldehyde due to H-bond. \({\rm{B}} \cdot {\rm{P}} \cdot \) order : \({\rm{RCOOH > ROH > RCHO}}{\rm{.}}\)

Assertion : Acetic acid in vapour state shows a molecular mass of 120 . Reason : It undergoes intermolecular hydrogen bonding.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Acetic acid has actual molecular mass of \(60 \mathrm{~g} /\) mol. But due to intermolecular hydrogen bonding and dimerization, its apparent molecular weight is \(120 \mathrm{~g} / \mathrm{mol}\). So the option (1) is correct.
