Definition

1. Adjective:
   • Of or related to an alkyl: Pertaining to or derived from an alkyl group, which is a univalent radical derived from an alkane by the removal of one hydrogen atom.

Usage

• The term "alkylic" is a specialized adjective used primarily in organic chemistry to describe compounds, properties, or reactions that involve alkyl groups.
• It is used attributively to modify nouns, such as "alkylic compound" or "alkylic substitution."

Examples

• Adjective:
  • The reaction proceeds via an alkylic intermediate.
  • Studying the alkylic derivatives of the compound revealed new properties.

Advanced Usage

• "Alkylic hydrogen": Refers to a hydrogen atom bonded directly to a carbon atom within an alkyl group.
  • The alkylic hydrogens are less acidic than vinylic hydrogens.
• "Alkylic carbon": Denotes a carbon atom that is part of an alkyl group.
  • The stability of the carbocation depends on the number of alkylic carbons adjacent to the positive charge.

Variants and Related Words

• Alkyl (noun): The univalent radical itself (e.g., methyl, ethyl).
  • Methane (CH₄) loses a hydrogen atom to form the methyl alkyl group (-CH₃).
• Alkylation (noun): A chemical reaction that introduces an alkyl group into a molecule.
  • The alkylation of benzene is an important industrial process.

Synonyms

• Alkyl-related: Pertaining to alkyl groups.
• Paraffinic: Relating to alkanes (paraffins), from which alkyl groups are derived; this is a broader, less specific synonym.

Notes

• "Alkylic" is a technical term with no common idioms or phrasal verbs associated with it.
• It is distinct from similar terms like "alkaline" (relating to bases) and "alkenic" (relating to alkenes).
