In which of the following compounds, does the substituent not exert its resonance effect?

A

`C_(6)H_(5)overset(+)(N)H_(3)`

B

`C_(6)H_(5)Cl`

C

`C_(6)H_(5)OH`

D

`C_(6)H_(5)NH_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`overset(+)NH_(3)` group exert only `-I` effect on account of higher electronegativity of `N` atom than the `C` atom of benzene ring and due to ists `+ve` charge. It is not able to exert `+R` effect as there is no long pair of electrons. It fails to exert `-R` effect beacuse `N` is not `pi` bonded to more electronegative atom.
