Question

The product formed when glycerol reacts PCl5 is?

Answer 1

Glycerol reacts with PCl5 to give 1,2,3-Trichloropropane or glycerol trichloride with Phosphorus oxychloride and HCl.

Answer 2

Explanation:

When glycerol reacts with phosphorus penta-chloride it gives glyceryl tri-chloride (1,2,3-trichloropropane) along with phosphoryl chloride and hydrochloric acid.

The reaction is given as:

$CH_2OH-CHOH-CH_2OH+ 3PCl_5 \rightarrow CH_2Cl-CHCl-CH_2Cl+POCl_3+3HCl$

1 mole of glycerol reacts with 3 mole of phosphorus penta-chloride to give 1 mole of 1,2,3-trichloropropane , 1 mole of phosphoryl chloride and 3 moles hydrochloric acid.
