Question

Given below are two statements :

Statement I: \(H_2Se\) is more acidic than \(H_2Te\).

Statement II: \(H_2Se\) has higher bond enthalpy for dissociation than \(H_2Te\).

In the light of the above statements, choose the correct answer from the options given below.

(1) Both statement I and Statement II are false.

(2) Both statement I and Statement II are true.

(3) Statement I is true but Statement II is false.

(4) Statement I is false but Statement II is true.

Answer 1

Correct option is: (4) Statement I is false but Statement II is true.

Acidic strength: \(H_2Se < H_2Te\)

\(\Delta _{dis} H : \underset{[276 \ KJ/mol]}{H_2Se} > \underset{[238 \ KJ/ mol]}{H_2Te}\)
