Which is the correct decreasing order of reactivity in the following ? (I) CH2=CH2 (II) CH3–CH=CH2 (III) (CH3)2C=CH2
A
III > I > II
B
III > II > I
C
II > III > I
D
I > II > III
Answer
III > II > I
Explanation
Solution
Electron releasing group and stability of carbocation will increase rate of an electrophilic addition reaction.
