Intermolecular forces are stronger than chemical bonds
Drag the substances to sort them according to their intermolecular force between their particles.
NO
CO2

HCl
C2H5OH
Dipole-Dipole forces
London forces
Hydrogen bonding forces
Draw two ammonia molecules (structural formulae). Indicate the force of attraction between them and identify this force by labelling it on the diagram
Which molecule(s) has hydrogen bonding between adjacent molecules?
Which molecule(s) has polar covalent bonds with London dispersion forces between adjacent molecules?
Which molecule(s) has non-polar covalent bonds with London dispersion forces between adjacent molecules?
Which molecule(s) has dipole-dipole forces between adjacent molecules?
