N2 b. NH3 c. CO d. CCl4. Key ConceptsThree types of force can operate between covalent molecules: Dispersion Forces also known as London Forces (named after Fritz London who first described these forces theoretically 1930) or as Weak Intermolecular Forces or as van der Waal's Forces (namd after the person who contributed to our understanding of non-ideal gas behaviour). Therefore, we can compare the relative strengths of the IMFs of the compounds to predict their relative boiling points. 4 years ago.

Determine the kinds of intermolecular forces that are present in each element or compound. For example, it requires 927 kJ to overcome the intramolecular forces and break both O–H bonds in 1 mol of water, but it takes only about 41 kJ to overcome the intermolecular attractions and convert 1 mol of liquid water to water vapor at 100°C. View solution. After all, if the molecules in one liquid are held tightly together by a strong intermolecular force, this liquid would be expected to behave differently than a second liquid in which the molecules are held together very weakly.

This is due to _____ A. dipole-dipole forces … But for $\ce{CH3COOH}$ , the carbonyl carbon is polarized by an $\ce{-OH}$ group as well an $\ce{=O}$ group attached to it, thus increasing its effective polarization more than the alcohol. H-Br is a polar covalent molecule with intramolecular covalent bonding. b. These stronger intermolecular forces present between H 2 O molecules requires the supply of considerably more energy to break individual molecules from each other than is the case for H 2 S molecules - sufficient to give water a boiling point of 100 °C, while the weaker intermolecular forces present between H 2 S molecules results in a boiling point of only -60.3 °C (at 1 atm … With the shape of the molecule you have to draw the lewis dot structure of your molecule and look for all elements and "things" that are coming off the central atom.
