Important allotropic forms of phosphorus are white phosphorus, red phosphorus and black phosphorus. Among these which allotropic form is more reactive ? Why ? |
|
Answer» Solution :White phosphorus is the most reactive because of the following two reasons : (i) White phosphorus consists of `P_(4)` molecules which are HELD together by WEAK VAN der Walls forces of attraction. (ii) The `P_(4)` molecules have considerable ANGLE strain because in them PPP angle is just `60^(@)`. Therefore, due to considerable angle strain and weaker forces of attraction, white phosphorus is most reactive. |
