Consider the following compounds,

Which of the following statements(s) is/are incorrect regarding I and II?

Options

A. I sbows +R-effect whereas II shows -R-effect
B. I shows -R-effect whereas II shows +R-effect
C. Both I and II shows -R-effect
D. Both I and II shows +R-effect

Answer

A

Explanation

Due to ability of delocalisation of Ione pair of electron present on N-atom in aniline results it to show +R effects. Where as, unavailability of Ione pair of electron on N-atom in nitro benzene due to attachment of more electronegative O-atom results it to show -R-effect.
