Question

What is the name of a benzene ring that has a $C{O_2}{C_2}{H_5}$ - group attached and an $OH$ - group attached para to each other?

Answer 1

Hint: We have to know the aromatic compounds are those synthetic mixtures that contain at least one ring with pi electrons delocalized right around them. As opposed to intensifying that display aromaticity, aliphatic mixtures come up short on this delocalization. We must have to know that the expression "fragrant" was doled out before the actual instrument deciding aromaticity was found, and alluded just to the way that numerous such mixtures have a sweet or charming scent; notwithstanding, not all sweet-smelling compounds have a sweet smell, and not all mixtures with a sweet scent are sweet-smelling.

Complete step by step answer:
We have to know that the setup of six carbon particles in aromatic compounds is known as a benzene ring, after the straightforward sweet-smelling compound benzene, or a phenyl bunch when part of a bigger compound.
As we know that this benzene ring that has attached to the $C{O_2}{C_2}{H_5}$ group. After the attachment of $C{O_2}{C_2}{H_5}$ the compound is called $propiophenone$. Then, in the $propiophenone$ structure, the alcohol group is attached para to each other. Then the name of the combined compound is called $1 - (4 - hydroxyphenyl)propan - 1 - one$ .
Therefore, the name of a benzene ring that has a $C{O_2}{C_2}{H_5}$ - group attached and an $OH$ - group attached para to each other is called $1 - (4 - hydroxyphenyl)propan - 1 - one$ .

Note: We have to know an atom is sweet-smelling when it sticks to four primary measures, the atom should be planar. The atom should be cyclic. We have to remember that each molecule in the fragrant ring should have a p orbital. The ring should contain pi electrons.
