A molecule is R(3)C-H. If H is replaced ...

A molecule is `R_(3)C-H`. If H is replaced by A `(R_(3)C-A)` and on doing so electron density on `R_(3)C` part increases, then A is :

A

electron attracting, then A is :

B

electron withdrawing group

C

electron repelling group

D

either of them.

Text Solution

Verified by Experts

The correct Answer is:
C
`underset("Therefore A is + I effect group")underset()(R_(3)C-Hoverset(-H)underset(+A)rarrR_(3)" "overset(delta-)C-overset(delta+)A,)`
