Question

Which of the following compounds would have significant intermolecular hydrogen bonding? $HF,C{H}_{3}OH,N_2{H}_4,C{H}_4$

• A. $HF,N_2{H}_4$
• B. $HF,C{H}_4,C{H}_{3}OH$
• C. $HF,C{H}_{3}OH$
• D. $C{H}_{3}OH,C{H}_4$

Answer 1

Answer: (A), (C)

The correct options are
A $HF,N_2{H}_4$
C $HF,C{H}_{3}OH$

A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen $\left(H\right)$ atom bound to a highly electronegative atom such as nitrogen $\left(N\right)$, oxygen $\left(O\right)$ or fluorine $\left(F\right)$ experiences attraction to some other nearby highly electronegative atom. $HF$, $N_2{H}_4$ and $C{H}_{3}OH$ have significant intermolecular hydrogen bonding.
Option A and B are correct.
