Question

Dehydration of alcohols take place more rapidly with POCl₃ than with H₂SO₄.

Select the correct statements(s) about the above dehydration reaction :

It does not involve carbocation.

It involves R – OPOCl₂ with –OPOCl₂ as a better leaving group.

It involves E₂ mechanism as pyridine base abstracts proton from the adjacent carbon as the same time at which –OPOCl₂ is leaving.

It is E1 reaction without formation of carbocation.
