We’re being asked to determine the intermolecular forces present between CH3NH2 molecules.
Recall that the boiling and melting point of a compound depends primarily on its mass and intermolecular forces. The types of intermolecular forces (IMF) are:
1. Hydrogen bonding – occurs in compounds where hydrogen is directly connected to an electronegative element such as N, O, or F; strongest IMF
2. Dipole-dipole interaction – occurs between two polar covalent compounds; 2nd strongest IMF
3. Induced dipole interaction – occurs between a polar and a nonpolar covalent compound; 3rd weakest IMF
4. London dispersion forces – occurs in all compounds and is the primary IMF exhibited by nonpolar compounds; weakest IMF
What type(s) of intermolecular forces are expected between CH3NH2 molecules?
induced dipole forces
