उत्तर
Generally, nonmetals do not react with water, except halogens.
E.g. Chlorine on dissolving in water gives the following reaction:
\[\ce{\underset{\text{Chlorine}}{Cl_{2(g)}} + \underset{\text{Water}}{H2O_{(l)}} -> \underset{\text{acid}}{\underset{\text{Hypochlorous}}{HOCl_{(aq)}}} + \underset{\text{acid}}{\underset{\text{Hydrochloric}}{HCl_{(aq)}}}}\]
