1. What is the Boiling Point of Benzene?

The boiling point of benzene at standard atmospheric pressure (1 atm) is 80.1°C. This is the temperature at which benzene changes from liquid to gas phase under normal conditions.

2. Standard Conditions

The standard boiling point is measured at 1 atmosphere (101.325 kPa) pressure. This value is well-established in chemical literature and represents the temperature at which the vapor pressure of benzene equals the atmospheric pressure.

3. Importance of Boiling Point

Details: The boiling point is a fundamental physical property used in chemical identification, purification processes, and industrial applications. For benzene, this property is crucial in petroleum refining and chemical manufacturing processes.

4. About Benzene

Chemical Properties: Benzene (C₆H₆) is an aromatic hydrocarbon with a hexagonal ring structure. It is a colorless, highly flammable liquid with a sweet odor, widely used as an industrial chemical and precursor to various materials.

5. Frequently Asked Questions (FAQ)

Q1: Why is the boiling point of benzene important?
A: It helps in separation processes, quality control, and understanding the physical behavior of benzene in various applications.

Q2: Does pressure affect the boiling point?
A: Yes, boiling point decreases with decreasing pressure and increases with increasing pressure according to Clausius-Clapeyron equation.

Q3: Is benzene hazardous at its boiling point?
A: Yes, benzene vapor is flammable and toxic. Proper safety measures should be taken when handling benzene near its boiling point.

Q4: How was this value determined?
A: Through precise experimental measurements under controlled laboratory conditions and verified by multiple scientific studies.

Q5: Can this value vary slightly?
A: Minor variations may occur due to measurement techniques, but 80.1°C is the accepted standard value in scientific literature.
