allyl group
Noun: - The univalent unsaturated organic radical C3H5; derived from propylene: A specific group of atoms (a radical) in organic chemistry with the formula C₃H₅, characterized by a carbon-carbon double bond. It is derived from propylene (propene) and serves as a fundamental structural unit in many organic compounds.
The term "allyl group" is used specifically in the fields of organic chemistry and biochemistry to describe this particular molecular fragment. It is always used as a noun to identify the radical itself or compounds containing it.
- Noun:
- The reactivity of the molecule is due to the presence of an allyl group.
- Garlic's distinctive odor comes from compounds containing an allyl group, such as allicin.
- In the reaction, the allyl group was transferred to the new substrate.
- "Allylic position": Refers to the carbon atom adjacent to a carbon-carbon double bond. This position is often involved in specific chemical reactions (allylic substitution).
- The hydrogen at the allylic position is more reactive.
- Allyl (adj): Pertaining to or containing the allyl group.
- Allyl alcohol is a simple compound with an allyl group attached to a hydroxyl group.
- Allylation (n): A chemical reaction that introduces an allyl group into a molecule.
- Allylic (adj): Relating to or characteristic of an allyl group or its position in a molecule.
- 2-Propenyl group: A systematic name for the allyl group, emphasizing its structure derived from propene.
- C3H5 radical: A formula-based synonym used in chemical notation.
The "allyl group" has a single, precise meaning in scientific terminology. It does not have idiomatic or phrasal verb uses, as it is a technical term from chemistry. Its importance lies in its role in organic synthesis and in natural products.
