Question

Complete the reaction Glycol on heating in the presence of ZNCL2

Answer 1

Answer:

ethylene glycol when heated in presence of anhydrous zncl2. ZnCl2 removes water from the reactant is its function.

Answer 2

Lets assume the glycol as ethylene glycol

Now when ethylene glycol reacts with anhydrous ZnCl2 water will remove ,

See the reaction ,    

                                                                                                                  O

                                                                                                                   ║                                                                                

 HO-CH2 CH2-OH  +  anhy. ZnCl2  + Δ   →    CH3= CHOH  →  CH3- CH

Now we can see that the Anhydrous ZnCl2 realese the water out anf form  acetaldehyde .
