Question

Which of the following is aromatic intermediate:
 A.Carbene
 B.Phenoxide
 C.Benzyne
 D.Pyridyl

Answer 1

Hint: We have to know that, the high solidness and the trademark synthetic conduct of benzene are called fragrant character or aromaticity, separately. Sweet-smelling rings are planar. Something else, an ideal covering of the ring particles' p orbitals, which structure the pi-electron cloud, is incomprehensible.

Complete answer:
We have to know that, electrophilic fragrant replacement reactions are natural reactions wherein an electrophile replaces a particle which is joined to an aromatic ring. Usually, these reactions include the substitution of a hydrogen molecule having a place with a benzene ring with an electrophile.
The aromaticity of the aromatic system is saved in an electrophilic sweet-smelling replacement reaction. For instance, when bromobenzene is shaped from the reaction among benzene and bromine, the dependability of the fragrant ring isn't lost.
Aryl halides or halo-arenes can be arranged through electrophilic fragrant halogenation responses of aromatic rings with chlorine, iodine, bromine. These responses by and large include the utilization of aluminum trihalides as catalysts.
There exist numerous kinds of electrophilic fragrant replacement reactions, the most significant of which include:
Friedel-Crafts alkylation reaction
Friedel-Crafts acylation reaction
Fragrant nitration reaction
Fragrant sulfonation reaction
Electrophilic sweet-smelling halogenation reaction
The aromatic framework utilized as a reactant in these reactions is normally benzene. The subtleties of these responses are recorded in this subsection.
During fragrant replacement, benzyne is framed as an intermediate.
Therefore, the correct option is (C) Benzyne.

Note:
We have to know that, an electrophilic fragrant replacement is a natural reaction wherein a molecule that is joined to a sweet-smelling framework (normally hydrogen) is supplanted by an electrophile.
