Chapter 13, Problem 13.27P

Interpretation Introduction

(a)

Interpretation:

The synthetic form for the given set of directions for carrying out the sequence of reactions is to be written.

Concept introduction:

The synthesis form is the balanced chemical equation that can be written in word format for carrying out the sequence of reactions with specified steps. For each synthetic step, the structures for the overall reactants, the reagents added, the overall products formed, and the required reaction conditions are to be mentioned.

The steps for writing the form of synthesis for the set of directions of reaction sequences are:

Identify the reactants, reagents, and products formed in each step from the names mentioned in the set of directions given for the reaction sequences.

The structures of reactants for the given names are to be drawn on the left side of the reaction arrow ($\to$).

The reagents used are to be written above the arrow, and the reaction conditions including the solvent, temperature, pH, time of reaction, etc. are to be written below the arrow. Reagents must be written in the form in which they can be added, not as they appear in the mechanism.

If more than one sequence is combined in one step, then the reagents are numbered according to their sequence, and the reagents can be written above as well as below the arrow. For the combined step, only the product of the final step is to be drawn and the intermediate products are omitted.

The structures of the products are to be drawn on the right side of reaction arrow ($\to$).

The inorganic by-products and leaving groups are often irrelevant to the synthesis and are omitted.
