List the following alkenes in decreasing order of reactivity towards e

1.	List the following alkenes in decreasing order of reactivity towards electrophilic addition: (i) = (ii) (iii) = (iv) =CHCl Explain your answer.
Answer» ALKYL groups, DONATION of electrons makes the π bond to be more reactive and ALSO rich in the electron. Conversely, the electron withdrawing alkyl groups like Cl makes the π bond to be less reactive and also electron deficient. The reactivity in the electrophillic addition in decreasing order, 1. (Since two CH_3 group) 2. (Since one CH_3 group) 3. (Alkyl with Cl) 4. (Cl is bonded to carbon double bond)
