Chapter 10 Molecular Shapes are built from 5 basic arrangements Bond Angle: Angle formed by covalent bonds Linear Molecules : Atoms lie in a straight line. -All diatomic molecules are linear. Bond Angle: 180° Planar Triangular Molecules : A Central Atom sits in the center of a triangle formed by three other atoms. Bond Angle: 120° Tetrahedral Molecules : Four-sided geometric figure shaped like a pyramid with triangular faces. Central Atom lies in the center of a tetrahedron formed by four other atoms. Bond Angle: 109.5° NH 3 – Trigonal Pyramidal – 3 bonding domains, 1 nonbinding H 2 O -- Nonlinear, Bent – 2 bonding domains, 2 nonbinding Trigonal Bipyramidal : Consists of 2 trigonal pyramids that shape a common base. Central atom is bonded to 5 other atoms. Bond between 2 equatorial bonds in 120° and bond between equatorial and axial bond is 90° SF 4 – Distorted Tetrahedral – 4 bonding domains, 1 nonbinding ClF 3 – T-Shaped – 3 bonding domains, 2 nonbinding I 3 - – Trigonal Pyramidal – 2 bonding domains, 3 nonbinding Octahedral Molecules : An 8-sided figure, which you might think of as two square pyramids sharing a common base. Center atom is bonded to 6 other molecules Bond Angle: 90° BrF 5 – Square Pyramidal – 5 bonding domains, 1 nonbinding XeF 4 –Square Planar – 4 bonding domains, 2 nonbinding Molecular shapes are predicted using the VSEPR model
