Question

In each reaction box, place the best reagent or reactant from the list below. Stoichiometry is omitted.

Answer 1

Concepts and reason

A reaction sequence and the final product is given is given. The reactants along with the reagents need to be given. A chemical reaction involves the reaction between two or more substances. the reaction process is helped by the reagents that help in bringing about the transformation of the reactant into product.

Fundamentals

The given reaction sequence has the final product as alcohol and the intermediate product as a haloalkane. Thus, the reagents and the reactant need to be selected.

The reduction of ketones using mild reducing agents such as sodium borohydride gives alcohols.

The alcohols undergo substitution reaction on reaction with phosphorus tribromide, hydrogen bromide or sulphonyl chloride.

The reaction of Grignard reagents with esters give alcohols. Firstly, the ester is converted to ketone and then to alcohol. Hence, two moles of Grignard reagent reduce esters to alcohols.

The first reaction sequence is as follows:

Convert the 2-bromopropane to Grignard reagent and then react the product obtained with ethyl acetate as follows:

Ans:
