Problems and Solutions

 
Problem 1.1:
Paramagnetic materials, those with unpaired electrons, are attracted by magnetic fields whereas diamagnetic materials, those with no unpaired electrons, are weakly repelled by such fields. By constructing a molecular orbital picture for each of the following molecules, determine whether it is paramagnetic or diamagnetic.
 

a. B2
b. C2
c. O2
d. NO
e. CO
 
 
Problem 1.2:
Calculate the bond order for each of the following molecules (Hint: first draw a correlation diagram for each).
 

a. B2
b. C2
c. O2
d. NO
e. CO
 
 
Problem 1.3:
Predict the hybridization of the central atom in each of the following molecules.
 

a. CH4
b. HCCCH
c. IF4-
d. IF 4+
e. CH2O
 
 
Problem 1.4:
