... 1. The phosphorous trihalides (PX3, X = halogen) show the following variation in the bond angle X-P-X: PF3 = 96.3°, PCl3 = 100.3°, PBr3 = 101.0°, PI3 = 102°. The trend is generally attributed to the change in the electronegativity of the halogen. (a) Assuming that all electron domains (electron pair ...
