You have four molecules that each belong to a different homologous series. Each molecule has the same number of carbons. Which homologous series would demonstrate the lowest melting and boiling points?

• Esters

• Carboxylic Acids

• Alcohols

• Alkynes

Which molecule would have the lowest melting and boiling point?

•

• 
• 

Octane has a higher melting point than Heptane because...

• Octane is heavier than Heptane

• It has a higher Surface Area, so more opportunity for dispersion forces

• Octane is capable of dipole-dipole bonding and Heptane is not

• Octane can form dimers and Heptane cannot
