When ethanol is treated with PCl5, it undergoes a substitution reaction where the hydroxyl group (-OH) of ethanol is replaced by a chlorine atom. This results in the formation of ethyl chloride and phosphorous oxychloride as byproduct.

Chloroform (CHCl3) is the most non-polar among C2H5OH (ethanol), PCl5 (phosphorus pentachloride), and CHCl3. This is because the electronegativity difference between carbon and hydrogen is much smaller than between carbon and chlorine, making CHCl3 more non-polar.
The name of the compound PCl5 is phosphorus pentachloride.
The formula for phosphorus pentachloride is PCl5.
The common name of PCl5 is phosphorus pentachloride.
Phosphorus pentachloride is the correct name for PCL5.
