Dispersion is an intermolecular force that occurs in all bondings between elements. Dipole-dipole only occurs in polar molecules and is when the electronegativity is much higher on one side than it is the other. It is the attraction between a positive element and a negative element from another molecule. 0 Intermolecular forces (IMFs) • Hold molecules together • Much weaker than intramolecular forces • Intramolecular bonds are usually 100x or even 1000x stronger *(kJ are units of energy like Calories; 1Cal= 4.184kJ) • 1000cal= 1Cal • 1cal =4.184J. 0 Figure 14.2: Intermolecular forces exist between molecules. Bonds exist within molecules. F2 is a non-polar molecule and on weak Dispersion forces will exist between these molecules. H2S on the other hand has an electronegativity difference between H and S (whereas there is none between F and F). which intermolecular forces would exist between molecules of: a. H2S b. H2O c.O2 d. SiH4 e. HCl f. CH3Cl g. CO2 h. NH3 13,209 results
Um, and this problem asks us what types of inter molecular forces are present in each of these six molecules. Um and so the section that precedes this question discusses internal forces. I'm and so primarily here we're concerned with three types, So they're either gonna be Vander Wal forces.
