1. Write the type of bonding present in each of the substances below. List the substances in order of increasing b.p.
          Ag     PH3   LiCl   SiO2

2. The b.p. of C2H is –87 oC, while that of CH3F is –78 oC. Account for this difference.

3. C2H5F and C2H5OH are two molecular substances with different boiling points. Identify the types of  IMF present, determine which substance has the higher boiling point and explain your choice.
