Chapter 9.2, Problem 10E

(a)

Interpretation Introduction

Interpretation:-The reason for washing the organic layer with a solution of sodium carbonate, in the work-up procedure, needs to be given.

Concept Introduction: The process of isolating and purifying products, formed during a chemical reaction, through multiple manipulations, is called a work-up procedure in Chemistry.

(b)

Interpretation Introduction

Interpretation:- In the work-up procedure, the organic layer was washed with a solution of sodium carbonate, and the reaction that occurs during this wash along with the gas that gets evolved needs to be written.

Concept Introduction:- An alkali when reacts with an acid, water is one of the products formed.

(c)

Interpretation Introduction

Interpretation: The organic layer is being washed with a solution of sodium carbonate, in a work-up procedure, and the reason regarding its importance to vent a separatory funnel for performing this wash, needs to be given.

Concept Introduction: A laboratory glassware apparatus that is used to separate liquids, from a mixture of the same into heterogeneous solvent phases with varying densities, is called a separatory funnel.
