Respuesta :
Hydrogen, ammonia, methane and water are also simple molecules with covalent bonds. All have very strongbonds between the atoms, but much weaker forces holding the molecules together. When one of these substances melts or boils, it is these weak 'intermolecular forces' that break, not the strong covalent bonds.
The intermolecular bonds are weaker than the intramolecular bonds.
The interactions that hold the atoms in a molecule together are intramolecular forces. The intramolecular forces are strong interactions.
The interactions present in between the molecules have been intermolecular interactions. Intermolecular interactions are weaker interactions and are formed by molecular polarity.
On heating, the bonds between the molecules break, while the bond within the molecule has been sustained. Thus, the intermolecular bonds are weaker than the intramolecular bonds.
The strength of bonds that holds the atoms in a molecule together has been much stronger as compared to the force that exists between different molecules.
