Nucleophilic displacement on a vinyl halide may be represented as

Which of the following vinyl halide is expected to follow this mechanism?

Options

A. `H_2C = CHBr`
B. `underset(CH_3)underset(|)(HC) = CHBr`
C. `(CH_3)_2C = CHBr`
D. `F_2C = CHBr`

Answer

D

Explanation

The electron-attracting F atoms stabilizes the intermediate carbanion. Hence, `F_2C =CH` Br will exhibit this mechanism.
