Biacetyl and acetoin are added to margarine to make it taste more like butter. Complete the Lewis structures, predict values for all COCOO bond angles, and give the hybridization of the carbon atoms in these two compounds. Are the four carbons and two oxygens in biacetyl in the same plane? How many bonds and how many _ bonds are there in biacetyl and acetoin?
Chem 120-07 Ch. 3: Molecules, Compounds, and Chemical Equations Definitions: Ionic Bond: a bond between a metal and a nonmetal; electrons are transferred Ionic Compound: a compound containing a metal and a nonmetal with a neutral charge Covalent Bond: a bond between two nonmetals; electrons are shared Molecular Compound: two or more elements that are covalently bonded Chemical Formula: the correct number of each element in a compound Empirical Formula: lowest whole number ratio of elements in a certain compound; rarely matches the molecular/chemical formula Molecular Formula: shows the actual number of atoms in a formula Structural Formula: shows the bonds between elements (single, d
