Question

How to convert 1- bromopropane to 2- bromopropane

Answer 1

The Dehydrohaogenation of 1-bromo propane with alcoholic KOH gives propene which on again hydrohalogenation with HBr gives 2-bromo propane due to Markonikove's rule for addition.

Answer 2

Answer: The conversion is given below.

Explanation:

To convert 1-bromopropane to 2-bromopropane, we need to follow some steps:

Step 1: Converting 1-bromopropane to prop-1-ene

When 1-bromopropane is reacted with alcoholic KOH, it results in formation of prop-1-ene. This reaction is known as hydrohalogenation reaction.

Step 2: Converting prop-1-ene to 2-bromopropane

When prop-1-ene is reacted with hydrogen bromide, the negative part goes to the carbon atom which has less number of hydrogen atoms. This rule is known as Markonikov's rule.

The conversion is given in the image below.
