Which has more bond angle PH3 or NF3?

NF3 has a greater bond angle than PH3. bcoz PH3 is a drago compound( i.e P doesnt allow its lone pair to take part in hybridisation due to less electronegative side atom attached with it, thus it forms about 90 angle between 3 P-H bonds.as..

Why bond angle in NH3 is greater than 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.

Which has greater bond angle PF3 or PH3?

In PH3 and PF3 bond angle of PF3 is greater as in PF3 back bonding takes place.

What is bond angle of NF3?

So the bond angle of NH3 is 107 dergrees, NF3 is 102.5 degrees.

Why bond angle of nf3 is less than NH3?

So in case of NH3 there will be more electron cloud on Central atom due to higher electronegativity of nitrogen than hydrogen . but in case of nf3 more will be electron cloud on the outer atom or surrounding atom hence its bond angle will be less then NH3.

Which one has more dipole moment NH3 or nf3?

As, both the N-H bond are in the same direction it adds to the bond moment of the lone pair, while N-F bond are in the opposite direction, so they partly cut the bond moment of the lone pair. Thus, dipole moment of NH3 is higher than that of NF3.

Why bond angle of NF3 is less than NH3?

Why does PF3 have greater bond angle than PH3 but Nf3?

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. This discussion on Why does pf3 have greater bond angle than ph3 but nf3 has lesser bond angle than nh3? is done on EduRev Study Group by NEET Students.

Which is more stable Nf3 or PF3?

P-F bond energy is 496 kj/mol. N-F bond energy is 278 kj/mol . thus the PF3 will be more stable than the NF3. Thank you for asking the question. NF3 and PF3 both compounds are polar and the valance electrons of the central element are 5.

Is the bond angle in PF3 related to Drago’s hypothesis?

WhilePF3 is a drago compound and has an angle slightly greater than 90 No it is not related with bond angle nor it is related to Drago`s hypothesis. Bond angle will be more in nf3 since it is directly proportional to en of central atom

What is the lone pair donor for PF3?

For PF3, the lone-pair donor is Fluorine as P has the vacant 3d orbital. This causes the bond angle to decrease as the bond length is shortened and thus there is less repulsion. If the central atom was the lone-pair donor then the bond length would increase and there would be greater repulsion, leading to greater bond angles.
