Which one of the following statements is incorrect ?

Options

AAtomic hydrogen is produced when ${H}_{2}$ molecules at a high temperature are irradiated with UV radiation.
BAt around $2000K,$ the dissociation of dihydrogen into its atoms is nearly $8 . 1 %$
CBond dissociation enthalpy of ${H}_{2}$ is highest among diatomic gaseous molecules which contain a single bond.
DDihydrogen is produced on reacting zinc with $HCl$ as well as ${NaOH}_{( aq ) .}$ .

Correct answer

B. At around $2000K,$ the dissociation of dihydrogen into its atoms is nearly $8 . 1 %$

Step-by-step solution

Atomic hydrogen is produced at high temperature in an electric arc or under ultraviolet radiations. The dissociation of dihydrogen at 2000 K is only 0.081%. H–H bond dissociation enthalpy is highest for a single bond for any diatomic molecule. Dihydrogen can be produced on reacting Zn with dil. HCl as well as NaOH (aq.).
