Ethyl group

Ethyl group

In chemistry, an ethyl group is an alkyl functional group derived from ethane (C2H6). It has the formula -C2H5 and is very often abbreviated -Et.

"Ethyl" was also the common designation in North America for high-performance commercial gasoline containing lead in the mid 20th century. The term comes from the name of the company, Ethyl Corporation, which manufactured the antiknock organometallic agent tetraethyl lead added to the gasoline.

Ethylation is the formation of a compound by introduction of the ethyl functional group, C2H5.
