PLEASE EXPLAIN!

primary, secondary, tertion least 2) (3 points) List the following carbocations in each set in order from most stable (numbering from 1) to least stable (numbering to 3): a. CH3CH2CCH CH3CH2CHCH2 CH3CH2CH2CH2 CHE b. CH3CHCHCH; CH3CHCHCH2 CH3CHCHCH? CH3

Answer 1

Н2 Hас- CH,CH2CH,CH2 - CH3 CH3CH2CHCH3 3 2 CHз least stable 1 most stable Explanation: tertiary carbocation is most stable than secondary carbocation which is more stable than primary carbocation. Н CH3 Hас- Hас- CH3 Hас- -CHз CH3 Вг CI 3 1 least stable most stable Explanation: carbocation having -CH3 on adjacent carbon is most stable due to more electron donating nature of methyl group and the structure having -Cl is more stable than structure having -Br group due to more electronegative nature of -Cl group TO+
