Explanation |
A. |
Stable due to resonance Destabilised due to inductive effect |
|
B. |
Destabilised due to inductive effect |
-/effect of F creates electron deficiency at carbon C+ |
C. |
Destabilised due to inductive effect |
+/effect of CH3 increases electron density at carbon C- |
D. |
A secondary carbocation stabilized due to hyperconjugation |
is attached to two carbon. It can also be stabilized by hyperconjugation. |
