Question

why is sulphuric acid not used during the reaction of alcohols with kI​

Answer 1

Because sulphuric acid is volatile in nature so it cannot be used okk

Answer 2

Since H2SO4 is an oxidizing agent, it oxidizes HI (produced in the reaction to I2).

Therefore, the reaction between alcohol and HI to produce alkyl iodide cannot occur.

Thus, sulphuric acid is not used during the reaction of alcohols with KI.

Instead, a non-oxidizing acid such as H3PO4 is used.
