Q. For the given carbanion intermediate,
RCH2−−CH−CH2−Cl
Choose the correct statement(s) :
RCH2−−CH−CH2−Cl
Choose the correct statement(s) :
- RCH2 group shows −I effect and hence stabilizes the carbanion.
- RCH2 group shows +I effect and hence destabilizes the carbanion.
- Cl group shows +I effect and hence stabilizes the carbanion.
- Cl group shows −I effect and hence stabilizes the carbanion.
Q. For the given carbanion intermediate,
RCH2−−CH−CH2−Cl
