Are all aromatic compounds sweet smelling?
Benzene derived products are well known to be pleasantly fragrant. There is a misconception amongst the scientific community, however, that all aromatics are sweet smelling and that all sweet smelling compounds would have a benzene ring in its structure.
Why do aromatic compounds smell?
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.
What is aromatic smell?
1 : of, relating to, or having aroma: a : having a noticeable and pleasant smell : fragrant aromatic herbs aromatic wines. b : having a strong smell The peat burns with a pungently aromatic smoke.
Are aromatic compounds odorless?

Are sweet smelling compound?
this is ester;a sweet smelling compound.it is used in making of perfumes and as flavouring agents. ester is the product when ethanoic acid (CH3COOH) reacts with absolute ethanol (CH3CH2OH) in the presence of an acid catalyst.
Do all molecules have smell?
Odorant molecules are not limited to carbon-containing compounds, as both organic and inorganic molecules may have a smell. For example, ammonia (NH3) is an inorganic compound that has a distinctive fishy scent [23]. Elemental chlorine gas (Cl2) has an acrid smell.
What is meant by aromatic compounds?
Aromatic compounds are those chemical compounds (most commonly organic) that contain one or more rings with pi electrons delocalized all the way around them. In contrast to compounds that exhibit aromaticity, aliphatic compounds lack this delocalization.
Which among the following has a sweet smell?
Detailed Solution. Option 4 is correct, i.e Easters. Esters are sweet-smelling substances that are used to make perfumes.
Which of the following compound has sweet smell?
Why don t ionic compounds have a smell?
Ionic compounds have enthalpies of vaporization and fusion on the order of 10 to 100 times higher than that of most covalent compounds. Because of the high enthalpy values, ionic solids tend to have low vapor pressure. In other words, they often don’t have an odor.
Why do molecular compounds smell?
According to odotope theory the smell of a molecule is then due to the pattern, i.e. the relative excitation of a number N of receptors to which it binds. Ethyl citronellyl oxalate, a molecule possessing a macrocyclic musk odour but linearin shape.
