Which of the following reactions are correct ?

A

B

(A) (trans) `underset(SN^(1))overset(overset(Theta)(OH))to(B)(cis)`

C

D

`(A) (trans) overset(H_(2)O)underset(SN^(1))to(C)(trans)`

Text Solution

Verified by Experts

The correct Answer is:
A, C
In (a) `SN^2` reaction proceeds by inversion of configuration, so the product is cis.
In polar solvent (e.g., `H_2 O`), `SN^1` reaction occurs, and reaction and racemisation take place if bond to the asymmetric `C` atom is broken.
So the correct answer for `SN^1` reaction is `(c)`.
