Question

Complete the following reaction given below

${\mathrm{PCl}}_3+{\mathrm{O}}_2\to$

Answer 1

• Phosphoryl trichloride$\left({\mathrm{POCl}}_3\right)$ is formed when Phosphorus trichloride$\left({\mathrm{PCl}}_3\right)$ reacts with oxygen$\left({\mathrm{O}}_2\right)$.
• This is a redox reaction.$\left({\mathrm{PCl}}_3\right)$ acts as a reducing agent and $\left({\mathrm{O}}_2\right)$ act as the oxidizing agent.
• A redox reaction can be defined as a chemical reaction in which electrons are transferred between two reactants participating in it. This transfer of electrons can be identified by observing the changes in the oxidation states of the reacting species

$\underset{\mathrm{phosphorous}\mathrm{trichloride}}{2{\mathrm{PCl}}_3\left(\mathrm{g}\right)}+\underset{\mathrm{oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{phosphoryl}\mathrm{trichloride}}{2{\mathrm{POCl}}_3\left(\mathrm{g}\right)}$
