ALLYL GROUP Meaning and
Definition
-
The allyl group, in organic chemistry, refers to a functional group consisting of three carbon atoms attached sequentially in a linear arrangement. It is denoted by the formula -CH2=CH-CH2-. More specifically, the allyl group is composed of a terminal double bond between two carbon atoms, followed by a single bond to another carbon atom. This arrangement creates a distinctive "H" shape appearance.
The term "allyl" originates from the alcohol, allyl alcohol, which was one of the first compounds to exhibit this functional group. Nevertheless, the allyl group can be present in various chemical compounds, including alcohols, ethers, amines, and halides. Additionally, it is frequently encountered in organic chemistry reactions such as nucleophilic substitution, elimination, and oxidation.
The allyl group serves as a remarkable carbon framework, displaying reactivity and stability due to the resonance effect induced by the double bond. This resonance allows the electron density to be distributed along the carbon chain, making the allyl group a moderately stable functional group. Many organic reactions involving the allyl group occur at the double bond, leading to the formation of diverse organic compounds.
Moreover, the allyl group finds applications in several industrial processes, such as polymerization and the synthesis of pharmaceuticals, agrochemicals, and fragrance ingredients. Due to its unique and versatile characteristics, the understanding and utilization of the allyl group are of great importance in the field of organic chemistry.

Etymology of ALLYL GROUP
The term "allyl" is derived from the word "allylic", which comes from the Latin word "alum", meaning "madder". "Allyl" specifically refers to a group of compounds known as "allyl compounds" or "allyl groups". The term was first coined in the mid-19th century when chemists began studying compounds derived from the madder plant (Rubia tinctorum), which was used in dye production. The madder plant contains a red pigment called "alizarin", and its derivatives were found to have a common structural feature called the "allylic system". This system consists of a double bond between carbon atoms, with one of the carbon atoms being directly attached to a side chain. Hence, the name "allyl" was given to the associated group of compounds, and it has been used ever since to describe similar chemical structures.
