Assertion A : H2Te is more acidic than H2S.

Question

Given below are two statements: 

One is labelled as Assertion A and the other is labelled as Reason R. 

Assertion A : \(H_2Te\) is more acidic than \(H_2S\). 

Reason R: Bond dissociation enthalpy of \(H_2Te\) is lower than \(H_2S\). In the light of the above statements. 

Choose the most appropriate from the options given below. 

(1) Both A and R are true but R is NOT the correct explanation of A. 

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

(3) A is false but R is true. 

(4) A is true but R is false.

Answer 1

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

Due to lower Bond dissociation enthalpy of \(H_2 Te\) it ionizes to give \(H^+\) more easily than \(H_2S\).
