Question

which category of compounds had a larger boiling point during the imf lab? match the compound with the correct imf that caused these data?
a) alcohols; dispersion
b) alkanes; hydrogen bonding
c) acetone; dipole - dipole
d) alcohols; hydrogen bonding
e) alkanes; dispersion

Explanation:

Alcohols have higher boiling points due to hydrogen bonding. Hydrogen bonding is a strong intermolecular force (IMF). Alkanes mainly have dispersion forces (a weaker IMF). Acetone has dipole - dipole forces (moderate strength). So, alcohols with hydrogen bonding would have a relatively larger boiling point.

Answer:

d) Alcohols; Hydrogen bonding
