Assertion (A) (S_N 1 ) hydrolysis of optically active 2- bromooctane results in the formation of (( ) ) - octan -2-ol. Reason ( ( 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 (( A ) )
- B(A) and (( R ) ) are correct but (( R ) ) is not the correct explanation of (( A ) )
- C(A) is correct but ((R) ) is not correct
- D((A) ) is not correct but ((R) ) is correct
Correct answer
A. (A) and (R) are correct, (R) is the correct explanation of (( 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_ N 1 ) reactions occurs through the formation of carbocation. And in (S_ 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.
