Ethanol reacts with phosphorus pentachloride at 23 oC to form hydrogen chloride, ethyl chloride (chloroethane) and phosphoryl chloride.
The chemical reaction is:
C2H5OH + PCl5 ==> C2H5Cl + POCl3 + HCl
Ethanol Phosphorus Ethyl Phosphorus Hydrogen
. Pentachloride Chloride Trichloride Chloride
The balanced chemical equation for the reaction between ethanol and phosphorous (V) chloride is:
`C_2H_5OH + PCl_5 -> C_2H_5Cl + POCl_3 + HCl`
Here, ethanol reacts with phosphorous chloride to produce ethyl chloride (also known as chloroethane), phosphorous trichloride and hydrochloric acid. This reaction takes place at 23 degrees Celsius.
This is a balanced chemical reaction since the number of atoms of each species is same on both sides (that is, reactants and products) of the reaction. For example, there are 2 atoms of carbon on the reactant side. Similarly, there are 2 atoms of carbon on the product side and hence the reaction is balanced in terms of carbon. Similarly, we have 6 atoms of hydrogen on both the reactant and product side of the equation. We can check for balance of other atoms as well.
Hope this helps.
