the weak chemical attraction is Hydroden bond while the stronger one is the Ionic bond
Covalent bonds will always be stronger then an dipole or charge attraction between molecules.
Forces of attraction have a stronger effect on the behavior of liquid particles.
A covalent bond is a chemical bond formed by the sharing of electrons within the molecule. Attractions between molecules are relatively weak because there is no formation of a chemical bond.
No, It is infact polar molecules that have higher melting points than non-polar molecules. Polar molecules have stronger intermolecular bonds called dipole-dipole forces. These forces are an attraction between the slightly positive end of one molecule with the slightly nehative end of another.
The stronger the forces the stronger the attraction between the molecules in the substance. This will tend to increase the temperature of phase changes, melting and boiling points.

carbon dioxide molecules
A large body of water molecules would typically not have a stronger attraction to fewer molecules. It would however attempt to pull smaller molecules toward it.
If you are asking about bonds of attraction between separate molecules, there are two kinds: dipole-dipole attraction and London dispersion force attraction. Dipole-dipole attraction is the stronger of the two, because the molecules in this case are polar, meaning that electrons are more often clustered at certain spots on the molecule and rarified at the opposite end, resulting in a greater charge on both ends (London dispersion forces are the weak forces of attraction between nonpolar molecules during random, fleeting moments of polarization). These forces are not to be confused with ionic attraction (which is attraction between ions, not molecules) and covalent bonds (which are the forces holding the individual atoms in a molecule together), both of which are stronger than any intermolecular force of attraction (with covalent bonding being the strongest of all bonds at the chemical as opposed to the nuclear level). Keep in mind, though, that the exact strength of attraction varies depending on the electronegativities of the different atoms in the molecule (but the weakest polar molecular bonds are, by definition, stronger than the strongest nonpolar molecular bonds).

The primary difference is a chemical bond is many times stronger than a attraction between molecules.
A covalent bond is a chemical bond formed by the sharing of electrons within the molecule. Attractions between molecules are relatively weak because there is no formation of a chemical bond.
The more polar the molecule, the stronger the force.

Compounds with Hydrogen bonds (Hydrogen bonded to N,O or F) will tend to have stronger bonds thus a higher BP, then the compounds with a stronger polarity determine bond strength, and finally dispersion forces (Molecular mass) So in conclusion if you have ex. HF and CO2 HF has a higher BP because it has a stronger bond than CO2 (it has a hydrogen bond, while CO2's strongest bond is a polar bond)
