The boiling points of various volitile organic compounds range from 50 to 260 degrees celsius.
The boiling points of compounds can be determined by considering the strength of the intermolecular forces between molecules. Compounds with stronger intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, tend to have higher boiling points. Additionally, the size and shape of the molecules can also affect the boiling point. By analyzing these factors, one can predict and compare the boiling points of different compounds.
The differences in melting and boiling points between ionic and covalent compounds are due to the strength of the intermolecular forces present. Ionic compounds have strong electrostatic forces of attraction between oppositely charged ions, resulting in higher melting and boiling points. Covalent compounds have weaker intermolecular forces such as London dispersion forces or dipole-dipole interactions, leading to lower melting and boiling points compared to ionic compounds.
Ionic compounds have high boiling points due to the strong electrostatic forces of attraction between the positively and negatively charged ions. These forces must be overcome to break apart the structure, requiring a significant amount of energy.
In fractional distillation, each fraction has a range of boiling points because it contains a mixture of compounds with varying boiling points. As the temperature increases during distillation, the compounds with lower boiling points vaporize first, followed by those with higher boiling points. The overlapping boiling point ranges in each fraction indicate the presence of multiple compounds rather than a single pure substance.
Liquid organic compounds are volatile because they change easily from liquid form to vapor. They will evaporate at temperatures of use and will cause oxygen in the air to be converted into smog-promoting ozone under favorable conditions.
Molecular compounds typically have lower boiling points compared to ionic compounds because of weaker intermolecular forces between molecules. The boiling points of molecular compounds increase with increasing molecular size and polarity. However, they generally have lower boiling points compared to ionic compounds due to the nature of the forces holding the molecules together.
All different covalent compounds have different boiling points.

Additionally, the size and shape of the molecules can also affect the boiling point. By analyzing these factors, one can predict and compare the boiling points of different compounds.
In fractional distillation, a group of compounds with different boiling points are separated based on their different boiling points. As the mixture is heated, the compounds vaporize at different temperatures and are collected in separate fractions according to their boiling points. This allows for the isolation of individual compounds from a complex mixture.
A substance that evaporates easily is called volatile. Volatile substances have low boiling points and readily transition from a liquid to a gas at normal temperatures.
Because they are not pure compounds !
The differences in melting and boiling points between ionic and covalent compounds are due to the strength of the intermolecular forces present. Ionic compounds have strong electrostatic forces of attraction between oppositely charged ions, resulting in higher melting and boiling points. Covalent compounds have weaker intermolecular forces such as London dispersion forces or dipole-dipole interactions, leading to lower melting and boiling points compared to ionic compounds.
As a generalization, yes.
Ionic compounds have high boiling points due to the strong electrostatic forces of attraction between the positively and negatively charged ions. These forces must be overcome to break apart the structure, requiring a significant amount of energy.
No mercury compound has a boiling point as high as this.
ionic
In general, organic compounds tend to have lower boiling points compared to inorganic compounds. This is because organic compounds are typically made up of lighter elements like carbon, hydrogen, and oxygen, which have weaker intermolecular forces. Inorganic compounds often contain heavier elements with stronger intermolecular forces, leading to higher boiling points.
