Z groups are electron withdrawing groups and decrease electron density on benzene ring. These groups (Z) are

Y groups donate the electron and increases the electron density on benzene ring. These groups (Y) are - OR -NHCOR -X, -NH2

Q. Identify the atoms or groups from the following that exhibit $- R$ effect and $+ R$ effect when present on benzene ring:

$Z$ groups are electron withdrawing groups and decrease electron density on benzene ring. These groups $(Z)$ are

$Y$ groups donate the electron and increases the electron density on benzene ring.

These groups $(Y)$ are $- OR$

$- N H COR - X, - N H_{2}$
