Question

How to do the intermolecular forces present relate to the size of the substances?​

Answer 1

Larger and heavier atoms and molecules exhibit stronger dispersion forces than do smaller and lighter atoms and molecules. F2 and Cl2 are gases at room temperature (reflecting weaker attractive forces); Br2 is a liquid, and I2 is a solid (reflecting stronger attractive forces).

Answer 2

Intermolecular forces:

Explanation:

• When intermolecular interactions are high, atoms, molecules, and ions are strongly attracted to one other and draw closer together. They are more likely to be found in condensed forms, such as liquid or solid.
• The greater the intermolecular interactions are, the closer the molecules are to one another when it comes to phase transitions. Good! For any given chemical, intermolecular forces are highest in the solid state and smallest in the gaseous state.
• The bigger the molecule, the larger the electron cloud and, as a result, the more intermolecular force is possible. Hydrogen bonding is known to occur when hydrogen is bonded to a highly electronegative element. And the strongest intermolecular force is hydrogen bonding.
