Therefore, one last lone pair accounts for the final … It's all very well to say that NH3 is 107º therefore PH3 will be as also - it just isn't.. there are other factors to consider such as the polarised nature of the N-H bond when compared to the P-H bond. Unfortunately, the reasoning behind this is mostly post-hoc; there's no real easy way for you to figure out that PH3 would have a 93.7 bond angle without actually measuring it or doing calculations. That is, in ionic compounds there is no intrinsically preferred direction in which a neighbour … Why is the Ge-F bond energy so much more than the Ge-Cl bond energy? Draw a line-bond structure for propene,CH3CH=CH2; indicate the hybridization of eachcarbon, and predict the value of each bond angle.
