VSEPR Theory Questions and Answers with complete solution

Tetrahedral - 4 things around the central atom, bond angle = 109.5° Trigonal Planar - 3 things around the central Atom, bond angle = 120° bent #2 - 4 things around the central atom, 2 lone pairs, bond angle <105° Linear - 2 things around the central atom, bond angle = 180° Trigonal pyramidal - 4 things around the central atom, 1 lone pair, bond angle <107° Lone pairs - Electron pairs not used in bonding Bent #1 - 3 things around a central atom, 1 lone pairs Bonding pairs - electrons shared between two atoms What do shapes predict? - properties of the molecules coordinate covalent bond - a covalent bond in which one atom contributes both bonding electrons If an ion has a charge of -3 - you add three electrons If an ion has a positive charge, - you subtract electrons Angle 116 - Bent #1Angle 109.5 - tetrahedral Angle 120 - Trigonal Planar Angle 180 - linear Angle 107 - Trigonal pyramidal Angle 105 - Bent #2
