Question

Which of the following is NOT a type of distillation?

• A. Simple distillation
• B. Fractional distillation
• C. Steam distillation
• D. Magnetic distillation

Hint:

Remember the three common types of distillation: simple, fractional, and steam. Any unfamiliar name like “magnetic distillation” likely indicates a distractor.

Answer 1

The Correct Option is D

Distillation is a widely used separation technique based on differences in boiling points of components in a liquid mixture. The main types of distillation include:
- Simple distillation: used when the boiling point difference between components is large.
- Fractional distillation: used for separating components with closer boiling points, often using a fractionating column.
- Steam distillation: used for temperature-sensitive compounds, where steam helps in the vaporization process.
However, magnetic distillation is not a recognized or standard method in chemical engineering or industrial processes. It does not exist in conventional literature or practical applications, making it the correct answer to the question.
