Question

Which of the following compounds would show evidence of the strongest hydrogen bonding?

• A. Propan-$1$-ol
• B. Propan-$2$-ol
• C. Propan-$1,2$-diol
• D. Propan-$1,2,3$-triol

Answer 1

The correct option is D Propan-$1,2,3$-triol

Order of strength of hydrogen bonding is:

Propane-1,2,3-triol $>$ Propane-1,2-diol $>$ Propan-1-ol>Propan-2-ol

Hence, $D$ is correct.
