2-Chloro-2-methylpentane

A type of haloalkane where a chlorine atom is bonded to a carbon in a 2-methylpentane structure, often used in organic chemistry studies.

Sodium Ethoxide

A sodium salt of ethanol, used primarily as a strong base in organic synthesis, formed by the reaction between ethanol and sodium metal.

Ethanol

A volatile, flammable, colorless liquid alcohol, widely used as a solvent, in medicine, and as the intoxicating ingredient in alcoholic beverages.
