- Molecules of the form AH2 can exist in two potential geometries: linear or bent. Construct molecular orbital diagrams for linear and bent CH2. Identify the relevant point group, include all of the appropriate symmetry labels and pictures, and fill in the electrons. Which geometry would you predict to be more stable, and why? (Please draw out the diagram and explain)arrow_forwardIndicate the variation in conductivity with concentration in solutions of strong electrolytes and weak electrolytes.arrow_forwardThe molar conductivity of a very dilute solution of NaCl has been determined. If it is diluted to one-fourth of the initial concentration, qualitatively explain how the molar conductivity of the new solution will compare with the first.arrow_forward
