Answer. <\/strong>The IUPAC name of the following compounds, Oxalic acid is ethane-1,2-dioic acid.<\/em> It is the simplest dicarboxylic acid and is commonly found in plants like spinach and rhubarb.<\/p>\n\n\n\n

Complete Answer: <\/strong><\/p>\n\n\n\n

The correct IUPAC name of oxalic acid is ethane-1,2-dioic acid. This compound is the simplest dicarboxylic acid, with two carboxylic acid groups (-COOH) attached to a two-carbon alkane chain.<\/p>\n\n\n\n

Structure and Formula of Oxalic Acid<\/strong><\/p>\n\n\n\n

Oxalic acid consists of two carbon atoms, and each carbon atom is bonded to a carboxylic acid group (-COOH). This gives the compound its strong acidic nature and places it in the category of dicarboxylic acids. The linear structure shows the two carboxyl groups directly connected through the carbon-carbon bond.<\/p>\n\n\n\n

Step-by-Step Explanation<\/strong><\/p>\n\n\n\n

Follow the steps below to determine the IUPAC name of the given compound, oxalic acid:<\/p>\n\n\n\n

1. Functional Group<\/strong>
As told previously, oxalic acid contains two carboxylic acid (-COOH) groups, which are strong acidic functional groups. These groups play an important role in determining the chemical behaviour and reactivity of the compound.<\/p>\n\n\n\n

2. Counting the Carbon Atoms<\/strong>
The molecule has two carbon atoms in its main chain. Therefore, the parent hydrocarbon is named ethane, which serves as the base name for compounds with two carbon atoms.<\/p>\n\n\n\n

3. IUPAC Rules Implementation<\/strong>
According to IUPAC nomenclature, when a compound contains two carboxylic acid groups, the suffix -dioic acid<\/em> is added to the name of the parent hydrocarbon. This indicates the presence of two acid groups in the molecule.<\/p>\n\n\n\n

4. IUPAC Name Formation<\/strong>
By combining the parent name ethane with the appropriate suffix -dioic acid,<\/em> the correct IUPAC name of oxalic acid becomes ethane-1,2-dioic acid.<\/p>\n\n\n\n
