Question

Which one of the following statements is incorrect? 2 2 (aq)

(A) Atomic hydrogen is produced when H  molecules at a high temperature are irradiated with UV radiation.
(B) At around 2000 K, the dissociation of dihydrogen into its atoms is nearly 8.1%.
(C) Bond dissociation enthalpy of H  is highest among diatomic gaseous molecules which contain a single bond .
(D) Dihydrogen is produced on reacting zinc with HCl as well as NaOH

Prashant Kotian · Accepted Answer

Atomic hydrogen is produced at high temperature in an electric are 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.)
