Red `P_4` is less valatile than white `P_4` Red `P_4` is more volatile than white `P_4` Reducing properties of hypo PHOSPHOROUSACID is DUE to O H bonds Hypo phospharic acid has one P - O - P bond
Solution :White phospharousis vey less stable a regular strain, while red phosphorous exists of CHAIN of `P_4` - UNITS so it is more stable and less volatile.
