10.2  Why is sulphuric acid not used during the reaction of alcohols with KI?

Answers (1)

We don't use sulphuric acid because it acts as an oxidising agent and the required alkyl iodide is not produced. The reactions are given below :-

                      2KI  +  H2SO4     →    2KHSO4  + 2HI

                      2HI  + H2SO4    →  I2  +  SO2  +  H2O
