Question

answer in correct order of reactivity..​

Answer 1

The correct order of increasing reactivity of c-x is c. a. b. d.

Answer 2

Answer:

A) IV>III>II>I

Explanation:

Halogens attached to aromatic rings have partial double bond character, hence breaking such bonds are difficult which shows that IV and III are not at top 2 positions(eliminates c and d option)

Since NO2 is a deactivating group/ meta-directing there is not much electron density at para position where halogen is attached

Hence that bond can be broken easily
