Statement (A)Sulphur vapour is paramagnetic. Statement (B) Reaction of dil. HCl with finely divided iron forms FeCl 3 and H 2 gas. The correct answer is (A) Statement (A) is correct, but (B) is wrong. (B) Both the statements are correct. (C) Statement (A) is wrong, but (B) is correct. (D) Both the statements are wrong.

Statement (A) Sulphur vapour is paramagnetic is correct statement as sulphur vapour has formula

S_{2}

, i.e. similar to

O_{2}

and

O_{2}

has two unpaired electrons in its anti-bonding molecular orbitals.

Statement (B) Reaction of

H Cl (dil.)

with finely divided iron forms

F e C l_{3}

and

H_{2}

gas is a wrong statement as the whole reaction is as follows:

F e + 2 H Cl (dil.) ⟶ F e C l_{2} + H_{2} (g)

The

H_{2} (g)

produced will prevent the formation of

F e^{3 +}

(i.e.

F e C l_{3})
