Q. 1. Write IUPAC name of the following compound :
`H_(3)C - underset(CH_(3))underset(|)(CH) - CH_(2) - underset(OH)underset(|)(CH)- underset(CH_(3))underset(|)(CH) - CH_(2) OH`

Explanation

To determine the IUPAC name of the given compound, we will follow these steps:

### Step 1: Identify the Parent Chain
The first step is to identify the longest continuous carbon chain in the compound. In this case, the longest chain consists of 6 carbon atoms.

### Step 2: Number the Carbon Chain
Next, we need to number the carbon chain. We will number the chain from the end that gives the lowest number to the functional group (OH group). Starting from the right end, we assign the following numbers:
1. Carbon 1: CH2 - OH (hydroxyl group)
