Boiling Point Determination Procedure for an Organic Compound
To determine the boiling point of an organic compound, a thermometer is inserted into a boiling water bath. The organic compound is then added to the boiling water bath, and the boiling point is determined.
The Meaning of Boiling Point
The boiling point is the temperature at which the vapor pressure of a liquid is equal to the atmospheric pressure. This means that the vapor pressure of the liquid is strong enough to push against the atmospheric pressure and cause the liquid to boil. The boiling point is different for different substances, and it can be affected by changes in the atmospheric pressure or the surrounding environment.
Organic Compounds
Organic compounds are those that contain carbon-hydrogen (C-H) bonds. The vast majority of all known chemicals are organic compounds. The study of organic compounds is called organic chemistry.
Organic compounds are found in all forms of life, and include the hydrocarbons that make up fossil fuels. The most common organic compounds are the hydrocarbons, which consist of only carbon and hydrogen. Alkanes, alkenes, and alkynes are the simplest hydrocarbons. They are called hydrocarbons because they contain only hydrogen and carbon atoms.
How to determine the Boiling Point of an Organic Compound?
The boiling point of an organic compound is the temperature at which the vapor pressure of the compound equals the atmospheric pressure. The boiling point is a function of the intermolecular forces between the molecules in the compound. The stronger the forces, the higher the boiling point.
The Procedure for Determining the Boiling Point of Benzene
A. The boiling point of benzene is determined by heating a sample of benzene in a sealed container until it boils.
B. The boiling point of benzene is then recorded.
C. The boiling point of benzene is then repeated.
D. The average of the two boiling points is then recorded as the boiling point of benzene.
The Procedure for Determining the Boiling Point of Benzaldehyde
Benzaldehyde, C 6 H 5 CHO, is a colorless liquid that has a characteristic almond-like smell. The boiling point of benzaldehyde is 572.6 degrees Celsius.
Determining the Boiling Point of an Organic Compound
The boiling point of an organic compound is a measure of how stable the molecule is. The higher the boiling point, the more stable the molecule is. The boiling point is also dependent on the strength of the intermolecular forces between the molecules.
Difference between Boiling Point and Melting Point of an Organic Compound
The boiling point of an organic compound is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. The melting point of an organic compound is the temperature at which the solid and liquid phases are in equilibrium.
Importance of Knowing Boiling Point of an Organic Compound
The boiling point of an organic compound is important because it helps to identify the compound and understand how it behaves. The boiling point is the temperature at which the vapor pressure of a liquid is equal to the atmospheric pressure.
