Question
Substituents on an aromatic ring can have several effects on electrophilic aromatic substitution reactions. Substituents can activate several effects on electrophilic aromatic substitution reactions. meta positions. through substitution, or inductively Substituents From the following lists, select the Substituents that have the indicated they are written as where X is the atom directly bound to property. The Substituents are written as -XY, where X is the atom directly bound to the aromatic ring.Explanation / Answer
O/P directed substitution:
-OH is activating in nature and donates electron to the ring
Hence it is O/P directing
-CF3 is deactivating due to -I and -H effect.
So, it is meta directing
-Cl is O/P directing as it gives its lone pair electrons to the ring
-COOH is meta directing as it withdraw electrons through resonance
-OCH3 is activating in nature and donates electron to the ring
Hence it is O/P directing
Answer:
-OH
-Cl
-OCH3
