Question

Which of the five basic geometries for molecules and ions has the largest bond angle? a. linear b. planar triangular c. tetrahedral d. square planar e. octahedral Which of these examples is not one of the five basic geometries for molecules and ions? a. planar triangular b. octahedral d. square planar e. trigonal bipyramidal The valence shell electron pair repulsion theory is based on the concept that a. only two electrons can occupy an atomic orbital. b. the position and speed of the electron are somewhat uncertain. c. electron pairs tend to stay as far apart as possible to minimize repulsions between them. d. electronegativity tends to promote the formation of polar bonds. e. electrons are added to the lowest energy atomic orbitals first. Application of the concepts of the VSEPR theory, suggests that the shape of the SOs molecule is a. trigonal pyramidal. square planar c. regular tetrahedral d. triangular planar. e. distorted tetrahedron. Application of the concepts of VSEPR theory leads to the prediction that the shape of the PCl3 molecule is a. bent. b. linear. c. regular tetrahedral. d. triangular planar e. trigonal pyramidal.
