The correct order of increasing stabilities of the following carbocations is
(i) allyl carbocation
(ii) ethyl carbocation
(iii) benzyl carbocation
(iv) isobutyl carbocation
- A (iv) < (iii) < (ii) < (i)
- B (iv) < (ii) < (i) < (iii)
- C (ii) < (iv) < (i) < (iii)
- D (ii) < (iv) < (iii) < (i)
Answer & Solution
Correct Answer
(B) (iv) < (ii) < (i) < (iii)
Step-by-step Solution
Detailed explanation
Stability of carbocation is explained by using many factors such as mesomeric effect, inductive effect and hyperconjugation effect. Order of stability is + M >+ X > + I Benzyl carbocation (iii) is most stable because odelocalisation of charge due to resonance of \(\pi\) -…
