Solution

The molecule capable of hydrogen bonding with other molecules of itself is NH3 (Ammonia).

Here's why:

Hydrogen bonding occurs when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. The electronegative atoms involved in hydrogen bonding are usually nitrogen, oxygen, or fluorine.

  1. CH4 (Methane): This molecule has no electronegative atoms (N, O, F), so it cannot form hydrogen bonds.

  2. HBr (Hydrogen Bromide): Although this molecule contains a hydrogen atom, bromine is not one of the three highly electronegative atoms that can form a hydrogen bond.

  3. H2 (Hydrogen): This molecule does not contain a highly electronegative atom, so it cannot form hydrogen bonds.

  4. NH3 (Ammonia): This molecule contains a nitrogen atom, which is highly electronegative and has a lone pair of electrons. Therefore, it can form hydrogen bonds with other NH3 molecules.
