Daily use candles (paraffin wax) contain

Options

A. Higher saturated hydrocarbon
B. Lower saturated hydrocarbon
C. Higher unsaturated hydrocarbon
D. Lower unsaturated hydrocarbon

Answer

**Step-by-Step Solution:**

1. **Understanding Paraffin Wax**: Paraffin wax is a type of hydrocarbon that is primarily composed of saturated hydrocarbons. Saturated hydrocarbons are those that contain only single bonds between carbon atoms.

2. **Identifying Hydrocarbon Types**: Hydrocarbons can be classified into:
- Saturated hydrocarbons (alkanes): These contain only single bonds.
- Unsaturated hydrocarbons: These contain one or more double or triple bonds.

3. **Characteristics of Paraffin Wax**:
- Paraffin wax is derived from higher alkanes, specifically those with a carbon chain length typically ranging from C20 to C40.
- These higher alkanes are solid at room temperature and are known for being colorless and odorless.

4. **Evaluating the Options**:
- **Option 1**: Higher saturated hydrocarbons - This is correct as paraffin wax is made up of long-chain saturated hydrocarbons.
- **Option 2**: Lower saturated hydrocarbons - This is incorrect as lower alkanes (C1 to C6) are gases or liquids, not waxy solids.
- **Option 3**: Higher unsaturated hydrocarbons - This is incorrect as paraffin wax does not contain unsaturated hydrocarbons.
- **Option 4**: Lower unsaturated hydrocarbons - This is also incorrect for the same reason as above.

5. **Conclusion**: Based on the characteristics of paraffin wax and the classification of hydrocarbons, the correct answer is that daily use candles (paraffin wax) contain higher saturated hydrocarbons.

**Final Answer**: Higher saturated hydrocarbons.
