Which molecule is capable of hydrogen bonding with other molecules of itself?Group of answer choicesCH4HBrH2NH3

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.
