Heteroarenes are aromatic compounds, where at least one methine or vinylene (-C= or -CH=CH-) group is replaced by a heteroatom: oxygen, nitrogen, or sulfur. [3] Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one ...
An aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor. For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose.
However, synthetic versions of the same compound as a natural essential oil are usually very comparable. Furthermore, natural oils are in many cases significantly more expensive than their synthetic equivalents. Aromatic oils are used in perfumery, candles, cosmetics, flavoring of food. [3] Some include (out of a very diverse range): Ylang ...
Aromatic properties have been attributed to non-benzenoid compounds such as tropone. Aromatic properties are tested to the limit in a class of compounds called cyclophanes. A special case of aromaticity is found in homoaromaticity where conjugation is interrupted by a single sp³ hybridized carbon atom.
Aromatic compounds, also known as arenes or aromatics, are chemical compounds that contain conjugated planar ring systems with delocalized pi electron clouds instead of discrete alternating single and double bonds. Typical aromatic compounds are benzene and toluene. They should satisfy Hückel's rule.
Eau de toilette (EdT): 5–15% aromatic compounds (typically ~10%). This is the staple for most masculine perfumes. Eau de cologne (EdC): 3–8% aromatic compounds (typically ~5%). This concentration is often simply called cologne. Eau fraîche: 3% or less aromatic compounds. This general term encompasses products sold as "splashes," "mists ...
An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants.Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove.
In organic chemistry, an aromatic amine is an organic compound consisting of an aromatic ring attached to an amine. It is a broad class of compounds that encompasses anilines , but also many more complex aromatic rings and many amine substituents beyond NH 2 .
