The IUPAC name of compound
`COOH-underset(COOH)underset(|)(CH)-COOH`

Options

A. Tricarboxy methane
B. Propane trioic acid
C. Tributanoic acid
D. Methane tricarboxylic acid

Answer

To determine the IUPAC name of the compound represented as `COOH-underset(COOH)underset(|)(CH)-COOH`, we can follow these steps:

### Step 1: Identify the Functional Groups
The compound has three carboxylic acid groups (–COOH).

**Hint:** Look for the functional groups in the structure first.

### Step 2: Determine the Parent Chain
Since there are more than two carboxylic acid groups, we will not consider them as part of the parent chain. Instead, we will identify the longest carbon chain that does not include the carboxylic acid groups.

**Hint:** The longest chain should not include the carboxylic acid groups when there are more than two.

### Step 3: Identify the Word Root
The longest carbon chain consists of one carbon atom (which is a methyl group, CH). The word root for one carbon is "meth".

**Hint:** The word root corresponds to the number of carbon atoms in the longest chain.

### Step 4: Determine the Suffix
Since there are three carboxylic acid groups, the suffix will be "tri-carboxylic acid".

**Hint:** The prefix "tri-" indicates that there are three carboxylic acid groups.

### Step 5: Combine the Name
Putting it all together, we have "methan" (from the one carbon) and "tri-carboxylic acid" (for the three –COOH groups). Therefore, the complete IUPAC name is "methan-1,2,3-tricarboxylic acid".

**Hint:** Ensure to include the correct numbering if applicable, but in this case, the numbering is implicit in the term "tricarboxylic".

### Final Answer
The IUPAC name of the compound is **methan-1,2,3-tricarboxylic acid**.
