Vedclass · Answer

(A) Groups that donate electrons to the aromatic ring via the $+M$ (mesomeric) or $+H$ (hyperconjugative) effect are known as ortho/para directing groups or activating groups.These groups increase the electron density specifically at the ortho and para positions,facilitating the attack of the electrophile at these sites.Among the given groups,$-OH$,$-OCH_3$,and $-NHCOCH_3$ are electron-donating groups and are ortho-para directing.Conversely,$-CN$,$-CO_2H$,and $-CHO$ are electron-withdrawing groups and are meta-directing.Therefore,the correct set is $I, IV, V$.

$I. -OH$	$II. -CN$
$III. -CO_2H$	$IV. -OCH_3$
$V. -NHCOCH_3$	$VI. -CHO$

Identify the ortho and para directing groups towards aromatic electrophilic substitution reactions from the following list:

$I. -OH$ $II. -CN$

$III. -CO_2H$ $IV. -OCH_3$

$V. -NHCOCH_3$ $VI. -CHO$
