Question

Consider the following statement

Statement-I: H₂Se is more acidic than H₂Te.

Statement-II: H₂Se has higher bond dissociation enthalpy, then H₂Te

In light of above statement, choose correct option.

(1) Statement-I is true and statement-II is false

(2) Statement-I is false and statement-II is true

(3) Both statement-I and statement-II are true

(4) Both statement-I and statement-II are false

Answer 1

Correct option is : (4) Both statement-I and statement-II are false

H₂Se is less acidic than H₂Te as bond dissociation enthalpy of H₂Te is lower then H₂Se and hence H⁺ is dissociated with more ease.
