We are being asked to identify the predominant intermolecular forces in each of these substances.
Intermolecular Forces (IMF) are the attractive forces between 2 molecules.
▪ deals with the attraction between an ion and a polar compound.
• Hydrogen Bonding
▪2nd strongest IMF
▪ exists anytime hydrogen is directly connected to fluorine, oxygen or nitrogen
▪3rd strongest IMF
▪ exists when two polar covalent compounds interact
• Dipole/Induced Dipole
▪4th strongest IMF
▪ deals with the attraction between a polar and nonpolar covalent compound
• London-Dispersion Forces/Van der Waals Force/Induced Dipole-Induced Dipole
▪ intermolecular force is found in all compounds, but it's the main intermolecular force of nonpolar covalent compounds
Identify the predominant intermolecular forces in each of these substances.
H2O, NH3, CH3C(OH)2CH3 KCl, CH4
