Question

Why do aromatic compounds smell?

Answer 1

Hint: Let us first know what aromatic compounds are. Aromatic compounds are made up of conjugated planar ring systems with delocalized pi-electron clouds in place of individual alternating double and single bonds. Aromatics and arenes are other names for them. Toluene and benzene are the greatest examples. Benzenoids and non-benzenoids such as furan, are the two types of aromatic compounds.

Complete answer:
The term "aromatic" has two meanings. It refers to a nice odour. or a chemical with a specific form of an electrical structure comprising a number of single and double bonds between carbon and sometimes other atoms in the molecule, as defined by organic chemists. This sort of chemical was given the name aromatic since many of them have strong pleasant odours.
Aromatic compounds smell for the same reason that non-aromatic compounds smell. They have a vapour pressure at ambient settings, which means that enough molecules are in the vapour phase to be detected by your olfactory system.
Because of their electrical configurations, different compounds have different odours. To form taste and smell sensations, the structure of the molecule and the distribution of electrons in it interact with molecules in the cells within our lips and nostrils.

Note:
It can be noted that the term "aromatic" was first coined to describe the odour of the compounds in question, but it has now been associated with greater stability induced by certain types of electron delocalization for many years. While some aromatic substances do have odours, there are numerous non-aromatic compounds that can be recognised by scent as well. It's really difficult to objectively describe odours.
