Comparing the boiling points of:

A) C3H8
B) C5H12
C) C2H5OH

and identify the folowing statements as either True or False:

Dispersion forces only for (A)
Boiling point (C) > Boiling point (A)
(B) exhibits hydrogen bonding
Boiling point (C) < Boiling point (A)
(A) exhibits hydrogen bonding
Boiling point (A) < Boiling point (B)
Boiling point (B) < Boiling point (C)
Dispersion forces only for (C)
Boiling point (B) > Boiling point (C)
Dispersion forces only for (B)
(C) exhibits hydrogen bonding
Boiling point (A) > Boiling point (B)

asked by Stefanie
  1. This should get you started since both A and B are hydrocarbons. C is an alcohol and will exhibit hydrogen bonding; therefore, it will boil higher than either A or C.
