in which of the following bond angle is maximum 1.Nh3 2.PCl4 3.BCl3 4.PCl6- Answer is Pcl6- how ?
Dear Student,
See in these type of questions try to get the hybridisation which will give you the hint about the geometry and then depending upon the geometry you can get the bond angles. Let's see their data by the below made table.
Now from the table its clear that 180 degrees is highest . So that's why PCl6- is having highest bond angle. I hope you get it.

| Molecule | Hybridisation | Bond angles |
| NH3 | sp3 | 107 degrees due to lone pairs present |
| PCl4 | sp3d | 90 degrees and 120 degrees |
| BCl3 | sp2 | 120 degrees |
| PCl6- | sp3d2 | 90 degrees and 180 degrees (the Cl-P-Cl in the axial positions) |
Now from the table its clear that 180 degrees is highest . So that's why PCl6- is having highest bond angle. I hope you get it.
