Which one of the following orders is correct regarding the inductive effect of the substituents

A

`-NR_(2)lt-ORgt-F`

B

`-NR_(2)gt-ORgt-F`

C

`-NR_(2)lt-ORlt-F`

D

`-NR_(2)gt-ORlt-F`

Text Solution

Verified by Experts

The correct Answer is:
c
The atom or group which has more power to attract electrons in comparision to hydrogen us said to have - I effect . Thus higher the electronegativity of atom stronger will be the - I effect . As electronegativity of N, O and F follow the order `NltOltF` hence based upon electronegative character order of - I effect is `-NR_(2)lt-ORlt-F`.
