Charge Vinyl And Charge Acetate

Vinyl cations were first proposed in 1944 as a reactive intermediate for the acid catalyzed hydrolysis of alkoxyacetylenes to give alkyl acetate. Acetate also describes the conjugate base or ion specifically the negatively charged ion called an anion typically found in aqueous solution and written with the chemical formula c 2 h 3 o 2 the neutral molecules formed by the.
