Describe the location of the maximum electron density of σ- and π-bonds. How is the difference in the spatial arrangement of the electron density of these bonds reflected on their strength?
The phosphorus trihalides (PX3) show the following variationin the bond angle X—P—X: PF3, 96.3°; PCl3, 100.3°;PBr3, 101.0°; PI3, 102.0°. The trend is generally attributedto the change in the electronegativity of the halogen.(a) Assuming that all electron domains are the same size,what value of the X—P—X angle is predicted by the VSEPRmodel? (b) What is the general trend in the X—P—Xangle as the halide electronegativity increases? (c) Usingthe VSEPR model, explain the observed trend in X—P—Xangle as the electronegativity of X changes. (d) Based onyour answer to part (c), predict the structure of PBrCl4.
