The central atoms of all the given conpund (O=SF2, O=SCl2, O=SBr2) are same and also have same hybidization (Sp3) hence we can applied Bent’s rule of Hybidization . According to bent rule more electronegative elements increases % P-character and decreases % S-character of that orbital in its attach. While in other orbital % S-character increase that why bond length decrease. Hence S=O bond length depends upon electronegativitiy of other attach atoms (F>Cl>I).
The overall S=O
bond length order is O=SBr2 > O=SCl2 > O=SF2O
