The main idea is that electrons don’t like to hang around near each other because they repel each other. As a result, the atoms in a molecule tend to separate as far as they can because their bonds repel each other. 2) For each of the following compounds, determine the bond angles, molecular shapes, and hybridizations for all atoms: a) carbon tetrachloride Carbon is tetrahedral, 109.50 bond angle, and sp3 hybridized. Chlorine is linear, has no bond angle, and is sp3 hybridized b) BH3 Boron is trigonal planar, 1200 bond angle, and sp2 hybridized. Hydrogen is linear, has no bond angle, and no hybridization c) silicon disulfide Silicon is linear, has a 1800 bond angle, and is sp hybridized. Sulfur is linear, has no bond angle, and is sp2 hybridized. d) C2H2 Carbon is linear, has a 1800 bond angle, and is sp hybridized. Hydrogen is linear, has no bond angle, and no hybridization. e) PF3 Phosphorus is trigonal pyramidal, has a bond angle of 107.50, and is sp3 hybridized. Fluorine is linear, has no bond angle, and is sp3 hybridized.
