Post by: tth on Nov 18, 2019

Question 1

Place the following in order of increasing X-A-X bond angle, where A represents the central atom and X represents the outer atoms in each molecule.

HCN

H2O

H3O⁺

◦ HCN < H3O⁺ < H2O
◦ H2O < HCN < H3O⁺
◦ H2O < H3O⁺ < HCN
◦ H3O+ < HCN < H2O
◦ H3O⁺ < H2O < HCN

Question 2

Determine the electron geometry (eg), molecular geometry (mg), and polarity of SO3.
◦ eg = trigonal planar, mg = trigonal planar, nonpolar
◦ eg = tetrahedral, mg = trigonal pyramidal, polar
◦ eg = tetrahedral, mg = tetrahedral, nonpolar
◦ eg = trigonal pyramidal, mg = bent, nonpolar
◦ eg = trigonal bipyramidal, mg = trigonal planar, polar
