Why is the bond angle of Cl2O greater than f2o?
In Case of Cl2O, delocalisation of lone pair (p) of electrons of oxygen to the vacant d-orbital of chlorine decreases the repulsion by lp and increases the repulsion between bp (bond pairs0. The bond angle thus becomes bery large (110.8∘).
Why is OCl2 polar?
OCl2 O C l 2 is a polar molecule. Both the bonds are polar, and the shape of molecule is bent due to lone pairs on oxygen atom. The resultant of two chlorine atoms is downward, and the resultant of the lone pairs is upward, but they are not completely cancelled by each other.
What is the bond angle in ph3?

In which of the following molecular species axial bond length is shorter than equatorial bond length?
Out of fluorine and chlorine, fluorine is more electronegative and will be strongly attracted to the central atom than the chlorine atom. The fluorine is positioned in the axial positions and hence the axial bond length is shorter than equatorial bond length in \[P{F_2}C{l_3}\].
Why PH3 has smaller bond angle than NH3?
This is because the size of the nitrogen is small than phosphorus. As a result, the force of repulsion between the bonded pair of electrons in PH3 is more than in NH3. Therefore, the bond angle in PH3 molecule is lesser than that in NH3molecule. List the uses of neon and argon gases.
Why does ocl2 have a higher bond angle than OCL?
OCl2 has higher bond angle. Since the electronegativity of F is more than Cl, it will attract the electrons towards itself and hence the shared pair of electron experience more repulsion in case of OCl2 (electrons b/w O-Cl, as they will be closer to O).
Why bond angles of molecules should not be ideal?
It is expected that the bond angles of the molecules should not be ideal and should deviate from 109.5° because VSPER theory (Valence shell electron pair repulsion theory) states that, when the central atom contains both bond pair and lone pair then the structure gets deviated as predicted from ideal shape of hybridization.
What is the angle of hydrogen bonding in H2O?
The actual angle in H2O is 104.5 deg, generally attributed to the fact that lone pairs (attracted by a single nucleus) are fatter than bonding pairs (attracted by two nuclei). Oxygen has two single bonds and two lone pairs in both H2O and OCl2.
Why is there Bond multiplicity in ocl2?
This type of bonding occurs in OCl2 because of the presence of the vacant 3d orbital in Cl. This type of π backbonding is not possible for OF2 and OH2 because 3d orbital absence in F and H. For π backbonding each O- Cl bond gets some π bond character in addition to σ bond and hence bond multiplicity occurs.
