Consider the carbocations shown below and identify the CORRECT statement. CH3CHCH3 CH₂CH-CH=CHCH3 (CH3)3CCH₂ A B O a. Carbocations, A and C, have electron-withdrawing groups which make the carbocations unstable. O b. The MOST stable carbocation is B because the carbocation, B, is stabilized by resonance delocalization which is absent in the other carbocations. O c. The MOST stable carbocation is B because B is a primary carbocation, which is more stable than the secondary and tertiary carbocations. Od. C is the MOST stable carbocation because C is a tertiary carbocation and A is a secondary carbocation.
