My textbook mentions that chlorination of alkanes by $\ce{SO2Cl2}$ is preferred over $\ce{SOCl2}$, but I didn't understand why.
Could someone explain which of the two reagents I should use in what situations, and briefly tell me why?
There is a similar question here: How does SO2Cl2 react with alcohols?
However the answers there did not completely clarify my doubts.
