Vedclass · Answer

(C) $(I)$ $CH_3O-CH_2^+$ is stabilized by resonance due to the lone pair on oxygen,making it more stable than the primary carbocation $CH_3-CH_2^+$. Statement $(I)$ is correct.$(II)$ $Me_2CH^+$ is a secondary carbocation,which is more stable than the primary carbocation $CH_3-CH_2-CH_2^+$ due to hyperconjugation and inductive effects. Statement $(II)$ is correct.$(III)$ $CH_2=CH-CH_2^+$ is an allyl carbocation,which is stabilized by resonance,making it more stable than the primary carbocation $CH_3-CH_2-CH_2^+$. Statement $(III)$ is correct.$(IV)$ $CH_2=CH^+$ is a vinylic carbocation where the positive charge is on an $sp$-hybridized carbon. This is highly unstable compared to the $sp^3$-hybridized primary carbocation $CH_3-CH_2^+$. Statement $(IV)$ is incorrect.Therefore,statements $(I), (II),$ and $(III)$ are correct.

Consider the following statements. Of these statements:
$(I) \ CH_3O-CH_2^+$ is more stable than $CH_3-CH_2^+$
$(II) \ Me_2CH^+$ is more stable than $CH_3-CH_2-CH_2^+$
$(III) \ CH_2=CH-CH_2^+$ is more stable than $CH_3-CH_2-CH_2^+$
$(IV) \ CH_2=CH^+$ is more stable than $CH_3-CH_2^+$
