Question

Assertion : Reaction of conc. H₂SO₄ on NaBr and NaI does not give HBr and HI. 

Reason : HBr and HI are oxidised by conc. H₂SO₄ to Br₂ and I₂.

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

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

The correct option is (a) Both A and R are true and R is the correct explanation of A.

Explanation:

H₂SO₄ when react with NaBr and Nal, give out Br₂ and I₂ as concentrated H₂SO₄ is a strong oxidising agent.
