Arrange in the order of descending bond angle in OF2, OCl2 and OBr2 with proper explanation.
OBR2>OCL2>OF2
Order of elctronegativity is:
F>Cl>Br
A more electronegative ion pulls the electron cloud towards itself and away from the central atom.
Hence the repulsion between the electron clouds of the 2 bonds joining the ion to the central atom decreases.
Therefore the bond angle decreases.
