Of the given 3 allotropes of Phosphorus – white, red and black, which is the most stable thermodynamically?
β-black Phosphorus is obtained by heating white Phosphorus in an inert atmosphere at very high pressures (4000-12000 atm) at about 473 K
β -black Phosphorus looks likeand is a good conductor of electricity. Black Phosphorus is regarded as the thermodynamically most stable allotrope and is also the least reactive!
α- black phosphorus is made by heating red P in a sealed tube at 453 K in an inert atmosphere. Neither white nor red Phosphorus are good conductors of electricity.
