Why PF3 has less bond angle than PCl3?
Friend the bond angle of PF3 is less than PCl3 because of stearic hindrance which is directly proportional to size of atom.
Why PH3 has less bond angle than H2O?
This is because the size of the nitrogen is small thanphosphorus . As a result , the force of repulsion between the bonded pair of electrons in PH3 is more than in NH3 .
Why there is decrease in bond angle?
Lone pair repulsion: Bond angle is affected by the presence of lone pair of electrons at the central atom. A lone pair of electrons at the central atom always tries to repel the shared pair (bonded pair) of electrons. Due to this, the bonds are displaced slightly inside resulting in a decrease of bond angle.
What is the bond angle of pcl3?

| Geometry | Trigonal Pyramidal |
Why is bond angle in NH3 more than PH3?
NH3 PH3 The bond angle in NH3 is larger than, in PH3 because the P−H bonds are longer and the lower electronegativity of P permits electron-density to be displaced towards hydrogen to a greater extent than in the case of NH3.
What is the bond angle of PCl3?
Why is the bond angle of PH3 less than that of PF3?
The bond angle of PH3 is less than that of PF3. Both PH3 and PF3 are pyramidal in shape. Both have one lone pair on phosphorous. But PF3 has partial double bond character due to back π-donation of electrons from p orbitals of F atom to empty d orbitals of P. This results in large repulsion between P-F bonds and hence bond angle is large.
Why is there no partial double bond character in PF3?
There is no partial double bond character possible in PH3 (due to lack of p-orbitals in H). The bond angle is more in PF3 due to lone pair-bond pair repulsion. As flourine is smaller in size and more electronegative than hydrogen, the bond pair of electrons is towards F.
Why is the bond angle in NH3 lower than in NF3?
In nh3 nitrogen is more electronegative so it will attract electrons towards it, as a result repulsion occurs so bond angle is more. And in Nf3 fluorine is more electronegative so repulsion will be less and bond angle is also lesser than nh3.
What is the difference between NH3 and Nf3 and PH3?
In nh3 nitrogen is more electronegative so it will attract electrons towards it, as a result repulsion occurs so bond angle is more. And in Nf3 fluorine is more electronegative so repulsion will be less and bond angle is also lesser than nh3. But in case of pf3 back bonding is possible so bond angle is more than ph3.
