how can i know what the names of the molecules in this list:C3H8. SO3, F2, KBr
(the numbers need to be little)
thanks.

Yanick said:SO3 is a sulfite anion and should have a -2 charge.
Borek said:Why not just sulfur trioxide?
Forces between molecules are the attractive or repulsive interactions that occur between molecules. These forces are responsible for the structure and properties of matter, including the physical state, melting and boiling points, and solubility.
The strength and type of forces between molecules can greatly influence the physical and chemical properties of substances. For example, substances with strong intermolecular forces tend to have higher melting and boiling points, while substances with weaker forces have lower melting and boiling points.
The main types of forces between molecules are dipole-dipole interactions, hydrogen bonding, London dispersion forces, and ion-dipole interactions. These forces range in strength from weakest (London dispersion forces) to strongest (ion-dipole interactions).
Intermolecular forces are weaker than chemical bonds, which are the strong forces that hold atoms together in a molecule. Intermolecular forces only occur between molecules, while chemical bonds occur within molecules.
The strength of intermolecular forces can be measured using various techniques, such as boiling point, melting point, and vapor pressure. These properties are influenced by the strength of the forces between molecules, with stronger forces resulting in higher boiling and melting points and lower vapor pressures.
