Vinyl halides are inert towards both S_(N^(1)) and S_(N^(2)) reactions – InterviewSolution

InterviewSolution

1.	Vinyl halides are inert towards both S_(N^(1)) and S_(N^(2)) reactions. Assign reason.
Answer» SOLUTION :Vinyl halides exhibit resonance. As a result the `C-X` bond has a partial double bond character. In `S_(N^(1))` reaction, `C-X` the bond is to cleave to FORM a carbocation INTERMEDIATE. IN `S_(N^(2))` reaction. the bond has to again cleave to accommodate the attacking nucleophile. this means that vinyl halides are RELUCTANT to respond to both types of reaction.
