Question

Among the following compounds $A$ and $B$ with molecular formula $C_9{H}_{18}{O}_3$, A is having higher boiling point than B. The possible structures of $A$ and $B$ are:

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

In option $b$, compound $A$ has extensive inter-molecular hydrogen bonding because of the 3 - OH groups. Whereas compound $B$ has $-OC{H}_3$ groups and therefore no inter-molecular hydrogen bonding is possible.
