Question

Does ${\mathrm{NH}}_3$ contain a hydrogen bond?

Answer 1

1. The bond is formed between hydrogen$\left(\mathrm{H}\right)$ and the three most electronegative atoms such as fluorine, oxygen, and nitrogen$(\mathrm{F},\mathrm{O},\mathrm{N})$.
2. A molecule of ammonia can give and receive up to three hydrogen bonds. Ammonia molecules joined together by hydrogen bonds makeup ammonia clusters.

Hence, ${\mathrm{NH}}_3$consist of three covalent bonds. Ammonia can participate in hydrogen bonding but does not have a hydrogen bond.
