Bonus question/statement: Also I'm imagining the whole molecules charges are … - Hydrogen bonding is strongest attraction. Does hydrogen bonding occur between to different electronegative atoms or do they have to be the same? This improved bonding leads to smaller PEO domains and lower gas permeability. Primary bonds have strength on an order of 300 to 500 kJ/mole, whereas secondary bonds are about 10 times weaker.
This means the molecules will be soluble in a polar solvent such as water.. Twitter. CH4 is a non polar molecule due to the tetrahedral shape and symmetry of bonds, so it only exhibits weak dispersion forces, the weakest of all intermolecular forces.
