Which of the organic products of the following reactions has the least boiling point?

Options

A. `CH_(3)-CH_(2)-COOH underset(H_(2)O)overset(LiAlH_(4))to`
B. `CH_(3)-underset(O)underset(||)C-CH_(3)underset(H_(2)O)overset(NaBH_(4))to `
C. `CH_(3)-CH_(2)-CHO underset(H_(2)O)overset(NaBH_(4))to`
D. `CH_(3)-CH=CH_(2) underset(H_(2)O_(2)OH)overset((BH_(3))_(2))to`

Answer

B

Explanation

In (B), isopropyl alcohol is formed, which has lesser boiling point than propyl alcohol formed in A, C and D. because of lesser extent of H-bonding.
