Which one of the following statements is incorrect? [ JEE Main 2021, 31 Aug (Shift 2)]

Atomic hydrogen is produced when \(\mathrm{H}_{2}\) molecules at a high temperature are irradiated with UV radiation.

Bond dissociation enthalpy of \(\mathrm{H}_{2}\) is highest among diatomic gaseous molecules which contain a single bond.

Dihydrogen is produced on reacting zinc with \(\mathrm{HCl}\) as well as \(\mathrm{NaOH}(\mathrm{aq})\).

At around \(2000 \mathrm{~K}\), the dissociation of dihydrogen into its atoms is nearly \(8.1 \%\).
