Nbutyyliryhmässä

Nbutyyliryhmässä, or n-butyl group in English, is a four-carbon alkyl functional group with the chemical formula -CH2CH2CH2CH3. It is a straight-chain saturated hydrocarbon substituent. The "n" prefix indicates that the butyl group is attached to a larger molecule through its primary carbon atom, meaning the attachment point is at the end of the unbranched chain. This distinguishes it from other butyl isomers such as sec-butyl, isobutyl, and tert-butyl groups, which have different branching patterns. The n-butyl group is a common structural component in many organic compounds. It is formed by removing one hydrogen atom from n-butane. When attached to a parent molecule, it contributes to the overall nonpolar character of that molecule, influencing its solubility and physical properties. For instance, the presence of n-butyl groups can increase the lipophilicity of a compound. Examples of compounds containing the n-butyl group include n-butylamine and n-butyl acetate. The n-butyl group is a saturated hydrocarbon chain and therefore does not contain any double or triple bonds.
