'Stability of carbocations depends upon the electron releasing inductive effect of groups adjacent to positively charged atom involvement of neighbouring groups in hyperconjugation and resonace''.
Which of the following ions is more stable ? Use resonance of explain your answer.

A

A

B

B

C

Neither A nor B

D

Noe of the above

Text Solution

Verified by Experts

The correct Answer is:
A
Carbocation (A) is more stable than carbocation (B). Carbocation (A) is more planar and hence is stabilised by resonance while carbocation (B) is non-planar and hence it does not undergo resonance. Further, double bond is more stable within the ring in comparison to outside the ring

II. Read the following passage and answer questions 6-10 that follow : During organic reactions, a covalent bond between two carbon atoms or carbon atom and some other atom is broken and a new bond is formed. The fission of bonds can be homolytic or heterolytic forming free radicals, carbocations carbanions, carbenes, etc. This also depends upon the displacement, of electron in a bond and is governed by inductive effect, electromeric effect, reasonance and hyperconjugation.
