Question 1

Which two simple functional groups make carboxyl group?
◦ aldehyde and keto groups
◦ aldehyde and hydroxyl groups
◦ keto and hydroxyl groups
◦ ester and hydroxyl groups
◦ ester and ether groups

Question 2

Why does benzene have a much higher boiling point (80 °C) than hexane (69 °C), even though they have the same number of carbons?
◦ Benzene has fewer hydrogens than hexane.
◦ Benzene is much more polar than hexane which enhances the attractive forces between molecules and raises the boiling point.
◦ Benzene is planar and has delocalized electron density which increases the attractive forces between molecules and raises the boiling point.
◦ Hexane has more Kekulé structures than benzene.
◦ Benzene can covalently bond to another benzene molecule which increases its boiling point.
