Give decreasing order of the following towards NA reaction.
I. II.
III. IV.

A

`(I) gt (II) gt (III) gt (IV)`

B

`(IV) gt (III) gt (II) gt (I)`

C

`(II) gt (III) gt (IV) gt (I)`

D

`(I) gt (IV) gt (III) gt (II)`

Text Solution

Verified by Experts

The correct Answer is:
C

All are aldehydes, `-I` effect of Cl at C-2 at `C-3 gt` at C-4. More the `-I effect, more reactive is the aldehyde forwards NA reaction `[(II)gt(III)gt(IV)gt(I)]`.
