Answer 2

ketone

Ketones are used as building blocks in the production of many complex organic molecules. They're most commonly employed as solvent, especially in the dynamite, varnishes, paintings, and textiles industries. Ketones are also employed as preservatives, tanning agents, and hydraulic fluids. Ketones have the general formula CnH2nO. The simplest ketone has three carbon atoms, hence its formula is C3H6O, often known as propanone. It also can be written as CH3O||CCH3, where the ketone's carbon is listed alongside the hydrocarbon's carbon. As a result, ketones have the general formula CnH2nO.
