Question

Which of the following statements are correct statements?

• A. Carbocation is less $\overline{e}$ deficient than alkyl radical
• B. lsornerisation of a less stable carbocation to more stable carbocation by 1.2-Me shift is called Wagner-Meerwein rearrangement
• C. Isomerisation to a more stable carbocation is accompanied by decrease in potential energy
• D. Greater stability of benzyl, allyl, and $3^o$ carbocation is due to hyperconjugation

Answer 1

Answer: (B), (C), (D)

The correct options are
B lsornerisation of a less stable carbocation to more stable carbocation by 1.2-Me shift is called Wagner-Meerwein rearrangement
C Isomerisation to a more stable carbocation is accompanied by decrease in potential energy
D Greater stability of benzyl, allyl, and $3^o$ carbocation is due to hyperconjugation

Here, (a) is wrong: carbocation is more $\overline{e}$ deficient than $R^o$.
Further, (b), (c), and (d) are self-explanatory
