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

Text Solution

Verified by Experts

`H_(2)SO_(4)` being a strong Oxidizing agent, Oxidizes `I^(Ө)` to `I_(2)`. So, Sulphuric acid is not used during the reaction of alcohols with KI.
`KI+H_(3)PO_(4)to KH_(2)PO_(4)+HI`
`8KI+5H_(2)SO_(4)to 4K_(2)SO_(4)+4I_(2)+H_(2)S+4H_(2)O`
