Web5) What are the advantages of medicinal plants? 6) How many aromatic plants are there? WebSo, to qualify as an aromatic compound, the molecule needs to fit the following four criteria: First, the molecule must be cyclic. Which means, we’re looking for molecules with rings in them. The molecule must be planar. Or, in other words, the molecule must be flat. The molecule also must be fully conjugated.

Did you know?

Aromatic compounds, also known as "mono- and polycyclic aromatic hydrocarbons", are organic compounds containing one or more aromatic rings. The word "aromatic" originates from the past grouping of molecules based on smell, before their general chemical properties are understood. The current definition of aromatic compounds does not have any relation with their smell. WebA compound whose molecule contains one or more aromatic rings is called an aromatic compound. Thus, 2, 4, 5, and 7 are aromatic compounds. There are chemical and spectroscopic methods that can be used to experimentally determine whether a ring is aromatic or not. All aromatic rings share two structural features: 1. The ring is planar. 2.

WebSo far we have studied only aromatic compounds with carbon-containing rings. However, many cyclic compounds have an element other than carbon atoms in the ring. These compounds, called heterocyclic compounds, are discussed later. Some of these are … WebAromatic compounds consist of compounds that are cyclic, possess a conjugated system, satisfy Huckel’s law, and are commonly planar. As the name suggests, cyclic structures form rings, as opposed to branching chain structures. Aside from a ring shape, aromaticity involves a continuous pi system.

WebIf the compound is branched, the name is determined similar to that used for the alkanes. Example. CH 3-CH-CH=CH-CH3 CH3 This compound is named 4-methyl-2-pentene.
