Question

The products A and B obtained in the following reactions, respectively, are

3ROH + PCl₃ → 3RCl + A

ROH + PCl₅ → RCl + HCl + B

Options

• H₃PO₄ and POCl₃

• H₃PO₃ and POCl₃

• POCl₃ and H₃PO₃

• POCl₃ and H₃PO₄

Answer 1

H₃PO₃ and POCl₃

Explanation:

Alcohol on reaction with PCl₃ and PCl₅ always gives permanent side products H₃PO₃ and POCl₃ respectively.
