The systematic name of `C_(17)H_(35)COOH` is

Options

A. Heptadecanoic acid
B. Octadecanoic acid
C. Steric acid
D. Plamitic acid.

Explanation

To determine the systematic name of the compound with the molecular formula \( C_{17}H_{35}COOH \), we can follow these steps:

### Step 1: Identify the number of carbon atoms
The molecular formula \( C_{17}H_{35}COOH \) indicates that there are 17 carbon atoms in the hydrocarbon chain and one additional carbon atom in the carboxylic acid group (COOH). Therefore, the total number of carbon atoms is:
\[ 17 + 1 = 18 \text{ carbon atoms} \]

### Step 2: Determine the base name from the carbon count
The base name for a straight-chain alkane with 18 carbon atoms is derived from the prefix "octadec-" which corresponds to 18 carbons. The suffix for an alkane is "-ane", but since we are dealing with a carboxylic acid, we will use the suffix "-oic acid".

### Step 3: Combine the base name with the functional group
Since the compound contains a carboxylic acid group (COOH), we replace the "-ane" suffix with "-oic acid". Therefore, the systematic name becomes:
\[ \text{Octadecanoic Acid} \]

### Final Answer
The systematic name of \( C_{17}H_{35}COOH \) is **Octadecanoic Acid**.
