WebbMelting and boiling points Molecular substances tend to be gases, liquids or low melting point solids, because the intermolecular forces of attraction are comparatively weak. … WebbAnswer (1 of 4): Carbon dioxide is a simple molecular gas. It consists of a carbon atom covalently bonded to two oxygen atoms. However, it has low boiling point because each individual molecule is joined together by weak intermolecular forces. These intermolecular forces are easily broken. That's...

WebbMelting point is defined as the point at which a solid state changes to a liquid condition. Boiling point is defined as the temperature at which air pressure equals the vapour pressure of a liquid. This is primarily used to describe solid-state chemicals or molecules. It refers to substances or molecules that exist in a liquid condition.
WebbSimple molecules have low melting and boiling points. The melting and boiling points of simple covalent compounds is usually low. This is because the intermolecular forces of attraction between molecules are weak and easy to overcome. Very little energy is required to overcome these forces.
