Question

The SN2 reaction with 1 Butanol and sodium bromide and sulfuric acid. what is the major byproduct?

Answer 1

In presence of sulfuric acid, i. e. acid catalysed 3.2 reaction of t-Butanol and sodium bromide gives 1- Beromobutane as the major product and water is. generated as a byproduct. The reaction is, OH + H₂SO4 + NaBr - The mechanism of the reaction is, -Br + H₂O -BM * B TOH₂ - Que + , Step! Nabe SN² step +H₂O = He 5 HO = Explanation: Step 1: From the above mechaniom it is clear that the basic butanol abstracts a Hatom from H₂SO4 and forms a good leavings group au which will produce H₂o after leavings butanot. Step 2: SN² step: Hor Naber ionizes to form Ber which attacks the protonated 1-butanos from back side and the product formed is 1- Beromo butane hearings a ₂0 molecule as a by product.

Hence, by the SN2 reaction with 1-Butanol and sodium becomide and sulfuric acid, the major byproduct formed is ₂0 and the major product formed is 1- Becomo butane,
