Chapter F, Problem F.16P

Interpretation Introduction

(a)

Interpretation:

The IUPAC name for the given structure of acid chloride is to be provided.

Concept introduction:

The IUPAC name of a compound is written from its structure. The IUPAC name is made up of three parts: prefix, root, and suffix. The suffix indicates the highest-priority functional group present. Its location is written as a prefix, unless redundant. The root is the longest continuous carbon chain that also includes the highest priority functional group. The carbon atom of the highest functional group must be the part of the longest continuous chain of carbon atoms, and the numbering starts from that carbon. Any other functional groups present are listed alphabetically as prefixes along with their locant numbers.

For acid chlorides, the highest priority functional group is the carboxylic acid chloride group ($\text{O=C-Cl}$), and the numbering starts from the carbon of the carboxylic acid chloride group. The suffix for the acid chloride group is oyl chloride. To write the root name of acid chloride, the last letter e of the corresponding alkane is replaced by oyl chloride.

If any chiral carbons are present, their absolute configurations are specified at the start along with the carbon number if necessary. A di, tri, etc., before a prefix or suffix indicates the number of instances of that functional group.
