Isopropuuryhmä

The term "isopropuuryhmä" is the Finnish word for the isopropyl group. The isopropyl group is a branched alkyl substituent with the chemical formula (CH₃)₂CH−. It is derived from propane by removing one hydrogen atom from the second carbon atom. It is also known as the 1-methylethyl group.

In organic chemistry, the isopropyl group is a common structural feature in many molecules. Its branched nature influences the physical and chemical properties of the compounds it is part of. For example, it can affect steric hindrance, which is the spatial arrangement of atoms in a molecule that can hinder chemical reactions. It also contributes to lipophilicity, meaning its tendency to dissolve in fats and oils.

Common examples of molecules containing the isopropyl group include isopropyl alcohol (also known as isopropanol or 2-propanol), a widely used solvent and disinfectant. Another example is isopropyl acetate, an ester used as a solvent. Many pharmaceuticals and other organic compounds also incorporate the isopropyl moiety. The systematic name for the isopropyl group, 1-methylethyl, emphasizes its structure as a propyl group with a methyl substituent on the first carbon atom of the propyl chain.
