Why is Sulphuric Acid Not Used During the Reaction of Alcohols with KI?
In the presence of sulphuric acid (H 2SO 4), KI produces HI `2KI + H_2SO_4 -> 2KHSO_4 + 2HI` Since `H_2SO_4`is an oxidizing agent, it oxidizes HI (produced in the reaction to I 2). `2HI + H_2SO_4 -> I_2 + SO_2 + H_2O` As a result, the reaction between alcohol and HI to produce alkyl iodide cannot occur. Therefore, sulphuric acid is not used during the reaction of alcohols with KI. Instead, a non-oxidizing acid such as H 3PO 4is used.
why is H2SO4 not used during the reaction of alcohols with KI
In the presence of sulphuric acid (H2SO4), KI produces HI Since is an oxidizing agent, it oxidizes HI (produced in the reaction to I2). As a result, the reaction between alcohol and HI to produce alkyl iodide cannot occur. Therefore, sulphuric acid is not used during the reaction of alcohols with KI. Instead, a non-oxidizing acid such as H3PO4 is used.
Why is sulphuric acid not used during the reaction of alcohols with KI?
Sulphuric acid is a good oxidising agent. When KI reacts with H_ can be used to produce alkyl iodides.
