Ketene, C2H2O, is a reactant for synthesizing cellulose acetate, which is used to make films, fibers, and fashionable clothing. (a) Write the Lewis structure of ketene. Ketene does not contain an OH bond. (b) Identify the electron-region geometry and the molecular geometry around each carbon atom and all the bond angles in the molecule. (c) Identify the hybridization of each carbon and oxygen atom. (d) Is the molecule polar or nonpolar? Use appropriate data to support your answer.
