Vinyl ethers are highly reactive towards electrophilic addition due to +M effect of alkoxy group

Q. The relative reactivity of the following towards Br2​ in chloroform is: (i) CH2​=CH−COCH3​ (ii) CH2​=CH−CH3​ (iii) CH2​=CH−O−CH3​ (iv) CH2​=CH2​

i > ii > iii > iv

iii > ii > iv > i

i > iii > ii > iv

iii > i > ii > iv
