Hybridization

The document contains a 20 question multiple choice test on topics related to chemical bonding and molecular geometry. The test covers hybridization of different molecules including SO4^2-, BeCl2, PCl5, benzene, ethyne, butane, and HCHO. It also asks about bond angles, shapes, numbers of sigma and pi bonds, and lone pair electrons in molecules like NH3, CH4, H2O, H2S, methane, ethene, BF3, and ethyne.
