Why red phosphorus is less reactive than white phosphorus? Calculate the pH of pOH of each solution? White phosphorus reacts with air vigorously that is it burns instantly in presence of oxygen and show phophorescence property ( it emits bright luminous green light in dark in prsence of small amount of oxygen ) , hence it is stable below 125'C and red phosphorus is stable above 125'C. White phosphorus has 4 atoms of P linked in tetrahedral shape, where as red phosphorus have amorphous network arrangement hence red phosphorus is more stable. Some of the most important uses of Phosphorus are: 1. This results in low melting point, and low boiling point, and high reactivity, as the bond angles, necessarily 60 ∘, are highly constrained in the tetrahedron.You can actually steam distill white (and yellow) phosphorus, and get a greasy distillate of white phosphorus … The occurrence of an element in more than one physical shape is called Allotropy. ...

Phosphorus exists in three forms in nature: (i) White phosphorus used as firecrackers, (ii) red phosphorus used in matches, and (iii) black phosphorus obtained by phase transformation of white phosphorus or red phosphorous at high temperature and pressure. The oxidation degree of phosphorus is -3, +3, or +5; on the other hand, the oxidation degree of phosphate is -3. The chief was seen coughing and not wearing a mask. White phosphorus is poisonous. For example, freshly prepared, bright red phosphorus is highly reactive and ignites at about 300 °C (572 °F), though it is more stable than white phosphorus, which ignites at about 30 °C (86 °F). They differ in their physical properties : 1) White P has 4 atoms linked in a tetrahedral shape and in Red P has two tetrahedral group attached to one … By exfoliating layered black phosphorus using the same method applied to obtain graphene from graphite, 2D black phosphorus … (i) white phosphorus (ii) red phosporus and (iii) balck phosphorus.

White phosphorus is less stable and therefore is more reactive than red phosphorus under normal conditions because of angular strain in the P 4 molecule where the angles are 60° only. The diverse physical types of a similar element are called Allotropes. As nouns the difference between phosphor and phosphorus The key difference between red and white phosphorus is that the red phosphorus appears as dark red colored crystals whereas the white phosphorus exists as a translucent waxy solid that quickly becomes yellow when exposed to light. If you heat white phosphorus upto 125'C in absence of air you get red phosphorus. The outer shell arrangement therefore resembles that of nitrogen, with three half-filled orbitals each capable of forming a single covalent bond and an additional lone-pair of electrons. Phosphorous forms multiple allotropes, the main two being White Phosphorous and Red Phosphorous, being named after their colors. (P block | class 12) Chemistry Explorers- Anshudeep tomar.
