Answer 1

Answer #1

Halogens are both ortho, para directing and ring deactivating in an electrophilic aromatic substitution reaction. This is mainly because of the following two reasons

1. The halogens are very electronegative, they cause inductive withdrawal.

2. The halogens have non-bonding electrons, they can donate electron density through pi bonding.

So, among the given groups, -I is both ortho, para directing and ring deactivating.

Substituents on an aromatic ring can have several effects on electrophilic aromatic substitution reactions. Substituents can activate or deactivate the ring to substitution, donate or withdraw electrons inductively, donate or withdraw electrons through resonance, and direct substitution either to the ortho/para or to the meta positions. From the following lists, select the substituents that have the indicated property. The substituents are written as -XY, where X is the atom directly bound to the aromatic ring. Activation of the ring towards...

Please help... Need a detail Mechanism of this reaction. Thanks... Electrophilic aromatic substitution describes the reaction where a hydrogen from a benzene ring is replaced by an electrophile. Halogenation, nitration, sulfonation, alkylation and acylation are all possible using this type of reaction. The electrophile attacks the pi electrons of the aromatic ring, yielding a benzenonium ion. The substituted aromatic product is obtained when a proton is lost, restoring the aromatic system. If there is a substituent on the aromatic ring...
