Question

A Grignard reagent is prepared by reacting cyclopentanol with first thionyl chloride and then magnesium in ether. The Grignard reagent is then reacted with acetaldehyde (ethanal) and the reaction mixture acidified. What is the major final product of this series of reactions?

Answer 1

Grignard reagent is a chemical compound having a halogen group along with magnesium and organic group.

Step-by-step explanation:

When cyclopentanol reacts with thiogyl chloride, it gives chlorocyclopentane as the product which on further reaction with magnesium metal gives Grigmard reagent as the main product.

A Grignard reagent is a chemical compound which have the chemical formula of R−Mg−X. Here, R is an organic group, Mg is magnesium and X is halogen. The organic group may be aryl or alkyl.

The reaction and the final product is given below at the attachment.
