MCQ

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : $H _2 Te$ is more acidic than $H _2 S$.
Reason R: Bond dissociation enthalpy of $H _2 Te$ is lower than $H _2 S$.
In the light of the above statements. Choose the most appropriate from the options given below.

A
Both A and R are true but R is NOT the correct explanation of A.
✓
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.

✓

Answer

Correct option: B.

Both A and R are true and R is the correct explanation of A.

(B)
Due to lower Bond dissociation enthalpy of $H _2 Te$ it ionizes to give $ H ^{+}$more easily than $H _2 S$.
