Eteenivetyyliryhmän

eteenivetyyliryhmän is the Finnish term for the ethyl group, a simple alkyl substituent with the chemical formula -CH2CH3. It is derived from ethane by removing one hydrogen atom. The ethyl group is a common functional group in organic chemistry and is found in a wide variety of organic compounds. It is often abbreviated as Et.

In nomenclature, the ethyl group is a prefix when it is a substituent on a parent hydrocarbon chain. For example, in ethanol, the ethyl group is attached to an oxygen atom. In ethane, the ethyl group is not present as a substituent but rather forms the entire molecule. The ethyl group is a saturated hydrocarbon fragment, meaning it contains only single bonds between carbon atoms and between carbon and hydrogen atoms. Its presence can influence the physical and chemical properties of a molecule, such as solubility, boiling point, and reactivity. For instance, increasing the number of ethyl groups in a hydrocarbon chain generally increases its lipophilicity. The ethyl group can participate in various chemical reactions, including oxidation, substitution, and addition reactions, depending on the overall molecular structure.
