JEE Main Chemistry Test- 10 - Question 7

Which of the following intermediates is formed in the reaction shown below ?

Detailed Solution for JEE Main Chemistry Test- 10 - Question 7

CH3CH2OH−→−HBrCH3CH2Br+H2OCH3CH2OH→HBrCH3CH2Br+H2O
In the given reaction, ethanol i.e. alcohol reacts with hydrogen bromide. The product formed is ethyl hydrogen bromide which is an alkyl halide along with water which is the by-product of the reaction.
In the reaction, an electron rich compound i.e. the bromine atom replaces the hydroxyl leaving group.
The reactions in which an electron rich compound replaces the leaving group is known as nucleophilic substitution reaction.
The mechanism of the reaction is as follows:
