Answer #1
Concepts and reason

The concept used to solve this problem is by using the given reagents, possible products will be formed in each step and then label it exactly in the given boxes in order to form the exact product.

Here, the starting reactant is ethyl benzene and the final product is (2-bromoethyl)benzene.

Fundamentals

Bromine molecule is used for bromination of alkene. Trans addition takes place.

Addition of HBr to the double bond forms an alkyl bromide.

Potassium tertiary butoxide is a sterically hindered base.

Bromination of alkane in the presence of sunlight gives radical substitution.

NBS (N-bromosuccinimide) is used for the allylic bromination.

The reaction is as follows:

CH2-CH3
Br—CH-CH3
NBS
ROOR
ethylbenzene
(1-bromoethyl)benzene

The reaction is as follows:

Br—CH-CH3
HC=
CH2
(CH3)3COʻK+
(1-bromoethyl)benzene
styrene

The reaction is as follows:

HC=
CH2
Hoc
HBr
ROOR
styrene
(2-bromoethyl)benzene

Ans:

The best reagents that are used for the conversion of ethylbenzene to (2-bromoethyl)benzene are as follows:

Reagent 1
Reagent 2
Reagent 3
Reactant
(ethylbenzene)
Step 1 product
Step 2 product
Final product
((2-bromoethylbenzene)
CH3
