Question

The correct order of alkene reactivity towards an electrophile is mentioned in-

• A. CH2=CH–Cl> CH2=CH–OCH3
• B. CH2=CHCl< CH2=CCl2
• C. Ethene > Propene
• D. CH2 = CH – OCH3> CH2=CH–$\underset{|}{C}H_{2} ⟽ O ⟽ H$

Answer 1

Answer: (D)

CH2 = CH – OCH3> CH2=CH–$\underset{|}{C}H_{2} ⟽ O ⟽ H$

Answer 2

Electron releasing group and stability of carbocation will decide rate of reaction in electrophilic addition reaction.
