Drawing the Lewis Structure for HCO 2-. Obviously, there are two double bonds. How do you think about the answers? The OH group is the larger than the H's so it won't have perfect tetrahedral geometry (the hydrogens will be slightly closer to each other than to the hydroxyl). Using VSEPR theory, this translates to trigonal bipyramidal electron pair geometry, and "see-saw" molecular geometry with a lone pair in the equatorial position. When did organ music become associated with baseball? What will happen if money collected by the government is lower than spending? CH 4 Molecular Geometry And Bond Angles.
