Which one of the following statements is incorrect ?
Select the correct option:
A
Atomic hydrogen is produced when $\mathrm{H}_2$ 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 $\mathrm{H}_2$ is highest among diatomic gaseous molecules which contain a single bond.
D
Dihydrogen is produced on reacting zinc with HCl as well as $\mathrm{NaOH}(\mathrm{aq})$.
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
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.)
