Provide an example of the boiling and melting points of different alcohols.

Different alcohols have varying boiling and melting points depending on their molecular structure and intermolecular forces.

For example, methanol has a boiling point of 64.7°C and a melting point of -97.6°C. This is due to its small size and ability to form strong hydrogen bonds with neighbouring molecules.

In contrast, ethanol has a higher boiling point of 78.4°C and a melting point of -114.1°C. This is because it has a longer carbon chain and can form weaker hydrogen bonds.

Propanol has an even longer carbon chain and therefore has a higher boiling point of 97.2°C and a melting point of -126.6°C.

As the carbon chain length increases, so does the boiling and melting point of the alcohol. This is because the intermolecular forces become stronger, making it more difficult to separate the molecules from each other.

Overall, the boiling and melting points of alcohols can be used to predict their physical properties and behaviour in different environments.
