Question

Which effect will be shown by the functional group present in the given molecule?

• A. $+M$ or $+R$
• B. $-M$ or $-R$
• C. $+I$
• D. Both (a) and (c)

Answer 1

The correct option is A $+M$ or $+R$

The functional group present in the given molecule is $-N{H}_2$ which contain lone pair electrons on $N$. This lone pair take part in resonance with double bond and hence shows $+M/+R$ effect.
