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?

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

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.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
