Consider the following structures `(A),(B),(C )` and `(D)`.





Which of the following statements is not correct?

Options

A. `(A)`and`(C )` are enantiomers
B. `(A)`and`(B)`are enantiomers
C. `(B)`and`(D)`are enantiomers
D. `(B)`and`(C )`are identical

Answer

C

Explanation

The priority order is `Br gt CIgt C_(2)H_(5) gt CH_(3)`.
`(A)` is `(S)`

`(B)` is `(R )`

`(C )` is `(R )`
`(D)` is `(R )`
Since both `(B)` and `(D)` have been assigned `R-`configuration, they are not enantiomers but are identical compounds.
