JEE MAIN - Chemistry (2024 - 30th January Evening Shift - No. 12)
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:
Both $$A$$ and $$R$$ are true and $$R$$ is the correct explanation of $$A$$.
Both $$A$$ and $$R$$ are true but $$R$$ is NOT the correct explanation of $$A$$.
$$A$$ is false but $$R$$ is true.
$$A$$ is true but $$R$$ is false.
Explanation
Due to lower Bond dissociation enthalpy of $$\mathrm{H}_2 \mathrm{Te}$$ it ionizes to give $$\mathrm{H}^{+}$$ more easily than $$\mathrm{H}_2 \mathrm{S}$$.
