Answer:
Most similar - sulphur
least similar- gallium
Explanation:
The compound formed when hydrogen reacts with oxygen is water. The chemical formula of water is H2O.
Water is very similar to H2S which is the compound formed when hydrogen reacts with sulphur. The bonds in water and H2S are both polar covalent bonds.
However, gallium is a metal and its hydride (GaH3) is least similar to water.
