Definition: A chemical group made up of two carbon atoms and five hydrogen atoms, often found in organic compounds.

Example: Ethyl alcohol is commonly known as ethanol.

Definition: To add an ethyl group to a chemical compound.

Example: Chemists often ethylate certain compounds to enhance their properties.

Definition: Describing a substance that has had one or more ethyl groups added to it, often used in chemistry.

Example: The ethylated compound showed different properties compared to its unmodified version.

Definition: To add an ethyl group to a compound, often used in chemistry.

Example: The chemist ethylated the compound to enhance its properties.

Definition: Relating to the process of adding an ethyl group to a molecule, often in chemical reactions.

Example: The ethylating agent was used to modify the compound's properties.

Definition: To introduce an ethyl group into a compound, often in a chemical reaction.

Example: The chemist is ethylating the compound to enhance its properties.

Definition: A type of liquid hydrocarbon that is mainly used to make another chemical called styrene.

Example: Ethylbenzene is an important ingredient in the production of polystyrene.

Definition: A colorless gas that is flammable and used in various industries, including the production of organic compounds and as a growth regulator in plants.
