Question

Rank the following compounds in increasing boiling point: 1 = Lowest boiling point, 3 = Highest boiling point. CH3OH CH4 CCI3

Jules Bruno · Accepted Answer

We are being asked to rank the following compounds in increasing boiling point: CH3OH, CH4, CCl3Intermolecular Forces (IMF) are the attractive forces between 2 molecules.• Ion-dipole▪strongest IMF▪ deals with the attraction between an ion and a polar compound.• Hydrogen Bonding[readmore]▪2nd strongest IMF▪ exists anytime hydrogen is directly connected to fluorine, oxygen or nitrogen• Dipole-Dipole▪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▪weakest IMF▪ intermolecular force is found in all compounds, but it's the main intermolecular force of nonpolar covalent compoundsBoiling Point and Intermolecular Forces▪stronger IMF → molecules are strongly held together▪more energy is required to break them apart → higher temperature required▪ therefore:    higher boiling (↑ BP) → stronger IMF (↑ IMF)Now, let’s analyze each compound given and determine the intermolecular forces present in each.CH3OH▪ CH3OH → -OH group in the compound ▪ can exhibit hydrogen bonding▪ has the 2nd strongest IMFCH4▪  all of them contains carbon and hydrogen only (hydrocarbons)▪ they are all nonpolar covalent compounds▪ only exhibit London-Dispersion forces (LDF)▪ has the weakest IMFCCl3▪ covalent bond between two nonmetal atoms ▪ polar bond between C (EN = 2.5) and Cl (EN = 3)▪ has a polar covalent bond▪ exhibit Dipole-dipole interaction▪  has the 3rd strongest IMFAnswer: The rank of the following compounds in increasing boiling point isCH4 < CCl3 < CH3OH
