Ncert Exercises & Solutions

Select the correct option based on statements below:

Assertion (A):	Hydrolysis of (-)-2-bromooctane proceeds with an inversion of configuration.
Reason (R):	This reaction proceeds through the formation of a carbocation.

1.	Both (A) and (R) are True and (R) is the correct explanation of (A).
2.	Both (A) and (R) are True but (R) is not the correct explanation of (A).
3.	(A) is True but (R) is False.
4.	(A) is False but (R) is True.

Hint: Follow S_N2 reaction mechanism.

Hydrolysis of (-)-2-bromooctane proceeds with inversion of configuration because the reaction follows S_N2 mechanism.

S_N2 mechanism is a single-step reaction in which both attacks of nucleophile and leave of leaving group takes place simultaneously.

In this reaction, carbocation is not formed as an intermediate.

Hence, Assertion is true but the reason is false.
