WebApr 9, 2024 · Red Phosphorus: Red phosphorus is a polymeric structure. It can be viewed as a derivative of P4 whereas one of the P-P bonds is broken. One of the additional bonds is formed with the neighbouring tetrahedron atom that results to form a chain-like structure. Red phosphorus may be formed by heating white phosphorus at 250 0C. WebPhosphorus 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.
WebJan 12, 2012 · Red phosphorus films were prepared by a vacuum deposition method. 100 mg of red phosphorus powder were put into a quartz glass tube (0.7 cm × 5.0 cm) with a quartz sheet (0.5 cm × 2.0 cm) inside. The system was sealed under vacuum. The glass tube was heated to 650 °C at 1 °C min −1 and kept at that temperature for 12 h. WebJan 30, 2024 · The red phosphorus molecule has a polymeric structure. It consists of chains of \ ( { {\rm {P}}_4}\) tetrahedra linked together. Red phosphorus is less reactive than white phosphorus because of its polymeric nature. Properties of Red Phosphorus Some important properties of Red Phosphorus are as follows:
WebRed Phosphorus. Red Phosphorus is the most common and concentrated source of Phosphorus. It is polymorphic in nature having a deep red color and a sort of grey luster. It is a derivative of the P4 molecule where one of the P-P bonds is broken. It is non-toxic and less reactive than the white Phosphorus. Red Phosphorus can react with water ...
