Laboratory chlorination of alkanes is often done with ……

Options

A. `SOCl_(2)`
B. `S_(2)Cl_(2)`
C. `SO_(2)Cl_(2)`
D. `SCl_(4)`

Answer

C

Explanation

When sulphuryl chloride `(Cl-underset(O)underset(||)overset(O)overset(||)S-Cl)` is used to chlorinate an alkane, an organic peroxide `ROOR` is used to chlorinate an alkane, an organic peroxide `ROOR` is used as an initiator. `SO_(2)` is also a product.
Step 1:
Step5: `Cl^(.)+R'Hrarr.^(.)R+HCl` then `(3),(4),(5)`, and so on. Steps `1` and `2` are initiation steps while steps 3,4, and 5, are propagation steps.
