In chemistry, the descriptor geminal (from Latin gemini 'twins'[1]) refers to the relationship between two atoms or functional groups that are attached to the same atom. A geminal diol, for example, is a diol (a molecule that has two alcohol functional groups) attached to the same carbon atom, as in methanediol.

The meaning of GEMINAL is relating to or characterized by two usually similar substituents on the same atom.

Geminal and vicinal are both terms used in organic chemistry to describe the arrangement of substituents on a molecule. Geminal refers to two identical substituents on the same carbon atom, while vicinal refers to two substituents on adjacent carbon atoms.

Jul 4, 2024 · Geminal dihalides, also known as alkylidene halides, are a type of organic molecule with a specific arrangement of halogen atoms. The main feature of these molecules is that two identical halogen atoms are attached to the same carbon atom within the hydrocarbon chain.
