What are the properties of white phosphorus?

The properties of white phosphorus are given below:

  • Less stable
  • Extremely reactive due to angular strain in P4 molecule(60°)
  • Readily catches fire on meeting with air
  • Give dense fumes when contact with air
  • It is poisonous, soft,low melting and waxy solid
    P4 +5O2→P4O10 (fumes)
  • P4 molecule is stable upto 1070K even in vapour phase

After 1070K P4 molecule dissociate to give P2
