What keep balloon inflated is not the molecular forces but the kinetics energy of the gas molecules made the molecules to bump and create the pressure inside the balloon.
The shape of the balloon is determined by the shape of the deflated rubber and the thickness of the rubber. The neck is usually thicker than the body, thus the body will expand far more than the neck. The pressure exerted upon the air by the balloon's elasticity creates the final inflated shape. If the thickness in the body of the balloon varies, the balloon will not be perfectly round. The thickness of the neck rubber forces the balloon to be more pear-shaped than spherical.
intermolecular forces
The force that lifts a hot air balloon is called buoyancy.

London dispersion forces (also known as van der Waals forces) hold molecular solids together. or Intermolecular forces

The liquid state is caused by intermolecular forces.
simple molecular compounds have weak forces of atraction.
van der Waals forces of attraction
intermolecular forces
Intramolecular forces are occured in ONE molecule whereas intermolecular forces are occured between molecules.
van der Waals forces of attraction
as inter molecular forces increase the evaporation point also increases as more heat is required to break the bonds
