In a nucleophilic substitution reaction \(R - Br + C{l^ - }\xrightarrow{{DMF}}R - Cl + B{r^ - }\) , which one of the following undergoes complete inversion of configuration?
- A \(C_6H_5CHC_6H_5Br\)
- B \(C_6H_5CH_2Br\)
- C \(C_6H_5CHCH_3Br\)
- D \(C_6H_5CCH_3C_6H_5Br\)
Answer & Solution
Correct Answer
(C) \(C_6H_5CHCH_3Br\)
Step-by-step Solution
Detailed explanation
\(C_6H_5CHCH_3Br\) being an optically active secondary alkyl bromide undergoes \(S_N2\) nucleophilic substitution reaction. Hence it undergoes complete inversion of configuration
