Assertion (A) S_N 1 hydrolysis of optically active 2- bromooctane...
Assertion (A) hydrolysis of optically active 2- bromooctane results in the formation of ((\pm)) - octan -2-ol.
Reason ((\mathrm{R})) The reation proceeds through a planar carbocation which can be attacked by the nucleophile from either side.
The correct answer is
Options
- A(A) and (R) are correct, (R) is the correct explanation of ((\mathrm{A}))
- B(A) and ((\mathrm{R})) are correct but ((\mathrm{R})) is not the correct explanation of ((\mathrm{A}))
- C(A) is correct but is not correct
- D is not correct but is correct
Correct answer
A. (A) and (R) are correct, (R) is the correct explanation of ((\mathrm{A}))
Step-by-step solution
Given, Assertion, (A) and the Reason (R), both are correct and the given Reason (R) is the correct explanation of the given (A). Because (S_{\mathrm{N}} 1) reactions occurs through the formation of carbocation. And in (S_{\mathrm{N}} 1) reaction both front as well rear attack of nucleophile at carbocation are possible. In 2-bromooctane, following carbocation is formed.
Thus, option (a) is the correct answer.
Thus, option (a) is the correct answer.
