Methanal vs Hexanone Boiling Point Comparison

In summary, the boiling point of methanal (formaldehyde) is -19°C and the boiling point of hexanone (methyl n-butyl ketone) is 127.5°C. Hexanone has a higher boiling point due to its larger and more complex molecular structure, which requires more energy to break intermolecular forces and transition to a gaseous state. This also affects its physical properties, such as being a liquid at room temperature and having higher viscosity and surface tension. Other factors that can affect the boiling point of these compounds include atmospheric pressure and impurities.

Related to Methanal vs Hexanone Boiling Point Comparison

What is the boiling point of methanal and hexanone?

The boiling point of methanal (also known as formaldehyde) is -19°C, while the boiling point of hexanone (also known as methyl n-butyl ketone) is 127.5°C.

Which compound has a higher boiling point, methanal or hexanone?

Hexanone has a higher boiling point than methanal. This is because hexanone has a larger and more complex molecular structure, which requires more energy to break the intermolecular forces and transition to a gaseous state.

Why does hexanone have a higher boiling point than methanal?

As mentioned before, hexanone has a larger and more complex molecular structure. This means that it has more intermolecular forces, such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces, which all contribute to the higher boiling point compared to methanal.

How do the boiling points of methanal and hexanone affect their physical properties?

The higher boiling point of hexanone results in it being a liquid at room temperature, while methanal is a gas. Hexanone also has a higher viscosity and surface tension compared to methanal, which are both characteristics of liquids.

Are there any other factors that can affect the boiling point of methanal and hexanone?

Yes, there are other factors that can affect the boiling point of these compounds, such as atmospheric pressure and the presence of impurities. Higher atmospheric pressure can increase the boiling points of both methanal and hexanone, while impurities can also alter the boiling point by affecting the intermolecular forces between molecules.
