Why does NH3 have a larger bond angle than PH3? Socratic

WebFor example, in a molecule such as CH 2 O (AX 3 ), whose structure is shown below, the double bond repels the single bonds more strongly than the single bonds repel each other. This causes a deviation from ideal geometry (an H–C–H bond angle of 116.5° rather than 120°). Four Electron Groups WebPlanar phosphido complexes usually have shorter M-P bonds and larger M-P-R angles. In the tungsten complex, the W-PHPh bond is 0.26 Å shorter than W-PEt 3 bond in the same complex, and the W-P-C angle is 140°. Another example is a ruthenium complex. In those complex, the Ru-PCy 2 bond is 0.11 Å shorter than Ru-PPh 3 bond and the Ru-P-C angle ... WebStructure of Phosphine. You can see that the electronic configuration of phosphine resembles ammonia. It has the structure of a pyramid. The bond angle H-P-H is = 93°. On the other hand, ammonia has pyramidal geometry with a bond angle of 107.8 0. Thus, we see that both these chemicals have a comparative bond angle.
