The IUPAC name for `CH_(3) - overset(C)overset(||)(C) - CH_(2) - CH_(2) - overset(C) overset(||)(C) - OH` is

Options

A. 1-hydroxypentane-1, 4
B. 1, 4-dioxopentanol
C. 1-carboxybutan-3-one
D. 4-oxopentanoic acid

Explanation

To determine the IUPAC name for the compound `CH3 - C(=C) - CH2 - CH2 - C(=C) - OH`, we will follow these steps:

### Step 1: Identify and Number the Carbon Chain
1. Identify the longest continuous carbon chain that contains the highest priority functional group. In this case, the longest chain has 5 carbon atoms.
2. Number the carbon chain starting from the end nearest to the highest priority functional group, which is the carboxylic acid (C(=O)OH).

**Hint:** Always start numbering from the end closest to the highest priority functional group.
