Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : $\mathrm{H}_2 \mathrm{Te}$ is more acidic than $\mathrm{H}_2 \mathrm{~S}$.
Reason R: Bond dissociation enthalpy of $\mathrm{H}_2 \mathrm{Te}$ is lower than $\mathrm{H}_2 \mathrm{~S}$.
In the light of the above statements. Choose the most appropriate from the options given below.
Select the correct option:
A
Both A and R are true but R is NOT the correct explanation of A.
B
Both A and R are true and R is the correct explanation of A.
C
A is false but R is true.
D
A is true but R is false.
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
Due to lower Bond dissociation enthalpy of $\mathrm{H}_2 \mathrm{Te}$ it ionizes to give $\mathrm{H}^{+}$more easily than $\mathrm{H}_2 \mathrm{~S}$.
