The word "allyl" is spelled with three Ls because it represents a specific chemical compound. In IPA (International Phonetic Alphabet), it is transcribed as /ˈælɪl/. The first sound, /æ/, represents the short "a" sound, followed by the sound /l/, which is pronounced with the tongue touching the alveolar ridge. The final sound, /ɪl/, is pronounced as "ill" and represents the suffix -yl that is commonly used in organic chemistry to indicate a specific group of atoms in a molecule.
Allyl is a term used to describe a specific organic functional group consisting of an unsaturated hydrocarbon chain with a double bond located adjacent to a single bond. It is derived from the name of the allyl group, which contains three carbon atoms bonded together, with one of the carbon atoms forming a double bond with one of its neighboring carbon atoms while the other two carbon atoms are bonded to single atoms or groups. The allyl group typically consists of the arrangement of CH2=CH-CH2-.
Allyl compounds are highly reactive due to the presence of the double bond. This double bond imparts characteristic chemical properties to allyl compounds, such as their tendency to readily participate in various chemical reactions, including addition, substitution, and elimination reactions. Allyl groups are often found in organic compounds, such as allyl alcohol, allyl chloride, and allyl isothiocyanate.
Allyl compounds are widely used in organic synthesis and have numerous applications. For example, they can be employed as intermediates or building blocks in the synthesis of various pharmaceuticals, agrochemicals, and other complex organic compounds. Additionally, allyl compounds are utilized in the production of resins, plastics, rubbers, and adhesives. Furthermore, the allyl group is of great importance in polymer chemistry, as it can participate in free radical polymerization reactions to form homopolymers or copolymers.
Overall, allyl is a functional group that plays a significant role in organic chemistry due to its reactivity and wide range of applications.

The word "allyl" comes from the Latin term "allium", meaning "garlic". It was derived from the Greek word "allion", also meaning "garlic". The name "allyl" was coined in the early 19th century to describe a group of organic compounds that were first isolated from garlic oil.
