Which of the following organic liquids can be purified by steam distillation ?
(i) Aniline
(ii) Turpentine oil
(iii) Essential oils
(iv) Glycerine

Options

A. (i), (ii), (iii), (iv)
B. (ii), (iii), (iv)
C. (ii), (i), (iv)
D. (i), (ii), (iii)

Explanation

To determine which of the given organic liquids can be purified by steam distillation, we need to analyze each option based on their volatility and the principles of steam distillation.

### Step-by-Step Solution:

1. **Understanding Steam Distillation**:
- Steam distillation is a technique used to purify volatile liquids. It involves the use of steam to vaporize the liquid, which is then condensed back into a liquid form. This method is particularly useful for substances that have high boiling points or are sensitive to heat.

2. **Evaluating Each Option**:
- **(i) Aniline**:
- Aniline is a liquid with a boiling point of about 184°C. It is somewhat volatile and can be purified by steam distillation.
- **(ii) Turpentine Oil**:
- Turpentine oil is a volatile liquid derived from pine trees, with a boiling point around 155°C. It can easily be vaporized and is suitable for steam distillation.
- **(iii) Essential Oils**:
- Essential oils are typically volatile compounds extracted from plants. They are designed to be distilled and can be purified using steam distillation.
- **(iv) Glycerine**:
- Glycerine (or glycerol) has a high boiling point (around 290°C) and is not volatile. It does not vaporize easily and cannot be purified by steam distillation. Instead, it requires vacuum distillation for purification.

3. **Conclusion**:
- Based on the analysis, the organic liquids that can be purified by steam distillation are:
- Aniline (i)
- Turpentine oil (ii)
- Essential oils (iii)
- Therefore, the correct answer is **(i), (ii), and (iii)**.

### Final Answer:
The organic liquids that can be purified by steam distillation are Aniline, Turpentine oil, and Essential oils.
