i. Draw the structures of all isomeric alcohols of molecular formula `C_(5)H_(12)O` and give their IUPAC names.
ii. Classify the isomers of alcohols in Q.No.3 (i) as primary, secondary, and tertiary alcohols.

Explanation

To solve the problem of drawing the structures of all isomeric alcohols with the molecular formula \(C_5H_{12}O\) and classifying them as primary, secondary, or tertiary alcohols, we can follow these steps:

### Step 1: Identify the possible structures
The molecular formula \(C_5H_{12}O\) indicates that we have 5 carbon atoms, 12 hydrogen atoms, and 1 oxygen atom. Since we are dealing with alcohols, the hydroxyl group (-OH) will be attached to one of the carbon atoms.

### Step 2: Draw the isomeric structures
1. **Pentanol (1-pentanol)**:
- Structure:
