How to solve: Predict the bond angles in the following molecules. 5 0. Conclusion. The bond length in P-H is 1.42 A. Furthermore, there are two bonding pairs instead of three this time, which is easier to compress, so this bond angle is even smaller. The angles are listed with the first atom having the smallest atomic number. PH3 ClF3 NCl3 BCl3 All of these will have bond angles of 120°. Why is that then? 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. But it is 107 degrees because the bonding pair occupies less space than the nonbonding pair. Yes IK, in this case it's not VSEPR but EN and BL.

Press question mark to learn the rest of the keyboard shortcuts. You'll just have to memorize them (or have a graphical calculator where you can store them :P) 0 HI Bond angle in PH4+ is higher than that in PH3 . yes PH3 has a triagonal pyramidal shape . The fact that the bond angle is nearly 90 degrees should tell you that the degree of hybridization in phosphine is almost negligible compared to the sp3-hybridized ammonia. So if NH3 is 107 degrees, can we say that PH3 is too? However, knowing that the bond angle is almost 90 degrees, we can justify it retroactively as a combination of decreased hydrogen steric effects due to the larger P-H bond distance and a lesser electron density on the less-electronegative phosphorous central atom. Bond angle in PH 4 + is higher than in PH 3. you cant really guess the bond angles as they are pretty close values. Hybridization of PH3 - Phosphine is sp hybridized.
