MCQ
Correct order of electrophilic substitution reaction is :
- A$a > b > c > d$
- B$d > b > a > c$
- C$b > a > c > d$
- ✓$b > a > d > c$
✓
Answer
Correct option: D.
$b > a > d > c$
d
The electrophilic substitution reaction depends upon electron withdrawing groups $(EWG)$ such as $- X,\,- CHO$ etc.
The electrophilic substitution reaction depends upon electron withdrawing groups $(EWG)$ such as $- X,\,- CHO$ etc.
andelectron donating groups $(EDG)$ such as $- OR ,\,- R$ etc. attached to the aromatic ring.
$EWG$ groups decreases the electron density on ring and $EWG$
groups increases the electron density on ring.
Therefore, the correct order is :
$b > a > c > d$
