Definition

Noun: 1. The substitution or addition of iodine atoms in organic compounds: A chemical reaction or process where iodine atoms are introduced into an organic molecule, either by replacing other atoms (substitution) or by adding to the molecule (addition).

Usage

This term is used primarily in chemistry to describe a specific type of halogenation reaction involving iodine. It denotes the process itself, not the resulting compound.

Examples

• The iodination of benzene requires a catalyst like nitric acid.
• Researchers studied the iodination of the aromatic ring to create new pharmaceutical intermediates.
• The rate of iodination was measured under different temperature conditions.

Advanced Usage

• Electrophilic iodination: A common type where an electrophilic iodine species attacks an electron-rich site in an organic compound.
• Radical iodination: A process involving iodine radicals, often initiated by light or heat.

Variants and Related Words

• Iodinate (verb): To introduce iodine into a compound.
  • Example: They attempted to iodinate the methane derivative.
