The final product obtained by the reaction between alcohol and phosphorus pentachloride is:

The reaction between alcohol and phosphorus pentachloride (PCl5) typically results in the formation of an alkyl chloride. This process involves the substitution of the hydroxyl group (-OH) in the alcohol with a chlorine atom.

Key Products of the Reaction

• Alkyl Chloride: The primary product is an alkyl chloride, which is a compound where the -OH group has been replaced by a chlorine atom.
• Phosphoric Acid: Another product formed during the reaction is phosphoric acid (H3PO4), which is a byproduct of the reaction.

Example Reaction

For instance, if you react ethanol (C2H5OH) with PCl5, the resulting alkyl chloride would be ethyl chloride (C2H5Cl), along with phosphoric acid.

Summary

In summary, the reaction between alcohol and phosphorus pentachloride yields an alkyl chloride and phosphoric acid, showcasing a common method for converting alcohols into more reactive halides.
