1.	Why is dinitrogen very unreactivecompared to phosphorus? (AI. 2008C)
Answer» Nitrogengas has complete octet for both the atoms and it isunreactivedue to the prsence of strong triple bond.On the other hand phosphorous has bonds with unstable angle strainscomparedto that ofnitrogendue to which it burns quickly,hence easily reacts. Phosphorusoccurs in at least 10 allotropic forms, the most common (andreactive) of which is so-called white (or yellow)phosphoruswhich looks like a waxy solid or plastic. It is veryreactiveand will spontaneously inflame in air so it is stored under water.
