Which of the following can form H -bond?

  • Correct answer
    A
    $\mathrm{NH}_3$
  • B
    $\mathrm{R}-\mathrm{CN}$
  • C
    $R-O-R$
  • D
    $\mathrm{R}-\mathrm{Br}$

Solution

The attractive electrostatic force between a hydrogen atom and an electronegative atom ( $\mathrm{F}, \mathrm{O}$, N ) is known as hydrogen bond. Thus, ammonia $\left(\mathrm{NH}_3\right)$ form hydrogen bond as Figure

Hence, the correct answer is option: 'A'.
