White phosphorus consists of discrete P 4 molecules. Moreover, the P 4 molecule is tetrahedral. This results in low melting point, and low boiling point, and high reactivity, as the bond angles, necessarily 60 ∘ , are highly constrained in the tetrahedron. This high angular strain makes white phosphorus unstable and highly reactive.You can actually steam distil white (and yellow) phosphorus, and get a greasy distillate of white phosphorus that is fiercely reactive, and must be stored under water. On the other hand, in red phosphorus, there is linking between phosphorus atoms across the material.So it is less reactive.
