Question

Why does vinyl chloride not form Grignard reagent?
Q.22. Which of the following does not form Grignard reagent on reaction with Mg in the presence of ether?
(1) Chloroethane
(2) 1-chloropropane
(3) Bromobenzene
(4) Vinyl chloride

Answer 1

Dear student

Vinyl chloride does not form grignard reagent and the reason behind it is that , The Mg of grignard reagent reacts with Cl and forms MgCl₂ an undesired product, as per grignard reagent it have to form R-MgX complex but it wont due to the complex formation as Mg-Cl .
hence the answer is justified .
