Which one of the following statements is incorrect?
Atomic hydrogen is produced when $\mathrm{H}_{2}$
molecules at a high temperature are irradiated with UV radiation.
At around $2000 \mathrm{~K}$, the dissociation of dihydrogen into its atoms is nearly $8.1 \%$.
Bond dissociation enthalpy of $\mathrm{H}_{2}$ is highest among diatomic gaseous molecules which contain a single bond.
Dihydrogen is produced on reacting zine with $\mathrm{HCl}$ as well as $\mathrm{NaOH}_{\text {(aa) }}$.
Correct Option: , 2
Atomic hydrogen is produced at high temperature in an electric are or under ultraviolet radiations
The dissociation of dihydrogen at $2000 \mathrm{~K}$ is only $0.081 \%$
$\mathrm{H}-\mathrm{H}$ bond dissociation enthalpy is highest for a single bond for any diatomic molecule.
Dihydrogen can be produced on reacting $\mathrm{Zn}$ with dil. $\mathrm{HCl}$ as well as $\mathrm{NaOH}$ (aq.)
