$\mathrm{F_2}$ is a stronger oxidizing agent than $\mathrm{Cl_2}$ in aqueous solution.
b
On hydrolysis ClF forms HOCl and HF.
c
$\mathrm{Cl_2}$ is more reactive than ClF.
✓
d
$\mathrm{F_2}$ is more reactive than ClF.

Correct Answerc

$\mathrm{Cl_2}$ is more reactive than ClF.

Detailed Solution

Strategy: Recall the structural arrangement of Sulphur atoms in its most stable allotrope.

Step 1: Rhombic Sulphur Structure At room temperature, the most stable form of Sulphur is $\alpha$ -sulphur (rhombic). It exists as molecules of $\ce{S8}$ .

Step 2: Shape The $\ce{S8}$ molecule forms a puckered, eight-membered ring known as a "crown" shape.

$\boxed{\text{Answer: (Option) [c] Crown shape}}$
