QJEEM21Che0b4: JEE Main 2021 Chemistry - Class 11 JEEM21Che0b4 Solution: Which one of the following statements is incorrect?
Which one of the following statements is incorrect?
Multiple Choice Options
- A Atomic hydrogen is produced when H2 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 H2 is highest among diatomic gaseous molecules which contain a single bond.
- D Dihydrogen is produced on reacting zinc with HCl as well as NaOH(aq).
Step-by-Step Verified 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.)
