Why ethanol has higher boiling point than alkane?
The hydroxyl groups in alcohol molecules are responsible for hydrogen bonding between the alcohol molecules. As greater energy is required to overcome these strong intermolecular forces, the melting points and boiling points of alcohols are higher than those of alkanes with a corresponding chain length.
Why does ethanol have a higher melting point?
Why does ethanol have a higher melting point than ethane? – Quora. Because ethanol has stronger intermolecular forces than ethane. Ethanol have hydroxyl groups (-OH), which allows for hydrogen bonding.
Why does ethanol have a low melting point and boiling point?
Why does ethanol have a lower boiling point than water? – Quora. There are less extensive hydrogen bonding between ethanol molecules than between water molecules, thus less energy is needed to vaporise ethanol than water and water has a higher boiling point than ethanol.
Why does ethane have a low boiling point?
Ethane is not polar due to its symmetry. Hence the only type of intermolecular forces present are the Van Der Waals/London Dispersion forces of attraction which are weak and require little energy to break hence ethane having a low boiling point.
Why does ethanol have higher boiling point than ethane?
The higher boiling point of ethanol indicates that it has stronger or a larger number of bonds than ethane. This will cause the oxygen to form intermolecular bonds with the hydrogen atoms on the other molecules to form hydrogen bonds.
Why does ethanol have a higher boiling point than ethane?
Why does ethanol have low melting point?
Both ethanol and ether have the same molecular mass, however, their melting points and boiling points are different due to the ethanol containing hydrogen bonding.
Why ethane has low melting point?
Alkanes have low melting or boiling points because of the very weak intermolecular forces between alkane molecules. Methane, ethane, propane, and butane are gases at room temperature. This means that there are more (relatively) stronger intermolecular forces between the molecules.
