Draw the structures of white phosphorus and red phosphorus. Which one of these two types of phosphorus is more reactive and why?

Explanation

White phosphorus is more reactive than red phosphours.
Then various `P_(4)` moleucles of white phosphorurs are held togather by weak Vander Wall's force of attraction. Which makes it very reactive. On the other hand, molecules of red phosphours are joined by covalent bonds to give a polymeric structure, which makes it very stable and less reactive.
