Chapter 17, Problem 17.51AP

Interpretation Introduction

Interpretation:

The structure of aluminum acetate which is used as an antiseptic ingredient has to be drawn.

Concept introduction:

In chemistry structure is the arrangement of chemical bonds between atoms in a molecule, specifically which atoms are chemically bonded to what other atoms with what kind of chemical bond.

According to IUPAC nomenclature, the naming of compound is determined by the priority of the functional group if more than one functional group is present. The carbon attached to the functional group having most priority should get the least number while naming the compound.

The order of priority is,

$\begin{array}{l}\text{carboxylic}\text{acid>esters>amides>aldehydes>ketones>}\text{alcolhols>thiols>}\text{amines}\text{>}\\ \text{ethers>alkenes>alkyl}\text{halides>alkanes}\end{array}$

Carboxylic acid: One $-OH$ group is attached to the carbonyl carbon atom of the compound. It is represented as $RCOOH$

The systematic name of the carboxylic acid derivatives is written by replacing the suffix name “–oic acid”.

Carboxylic acid salt: It is an ionic compound having a carboxylate acid anion and a metal cation. It is formed when a carboxylic acid and a strong base reacts giving water.

Metal salt of carboxylic acids are written as name of metal in prefix and base name with “-oate” suffix.
