Question

Convert n-propyl bromide into iso propyl bromide

Answer 1

n-propyl bromide reacts with alkaline KOH undergoes dehydro halogination to form propene.

CH3CH2CH2-Br + alc.KOH → CH3CH=CH2

propene reacts with HBr in the presence of peroxide to form isopropyl bromide. this ANTI MARKOWNIKOFFS addition

CH3CH=CH2 + HBr + peroxide → CH3CH2BrCH3

Answer 2

Answer: The conversion is given below.

Explanation:

To convert n-propyl bromide to iso-propyl bromide, we need to follow some steps:

Step 1: Converting n-propyl bromide to propene

When n-propyl bromide is reacted with alcoholic KOH, it results in formation propene. This reaction is known as dehydrohalogenation reaction.

Step 2: Converting propene to iso-propyl bromide

When propene is reacted with hydrogen bromide, it results in the formation of a iso-propyl bromide. This reaction is known as Markonikov's rule.
