In the vinyl carbocation, the positive charge is on the carbon atom with the double bond t… WebFinal answer. Step 1/3. 1) Primary carbon (1° carbon) cannot undergo SN A 1 reactions. This is because SN A 1 reactions involve the formation of a highly unstable carbocation intermediate, and primary carbocations are extremely unstable due to the lack of electron density on the carbon atom, as well as the increased steric hindrance.
