 |
||
| II. | Observations on a metal complex in which HD replaces 
were used to show that
is bound in 
without H-H bond rupture. If the dihydrogen complex has an H-H stretch at
 , what
would be the expected wavenumber of the HD complex? What should be the pattern
of the 
signal arising from coupling with D in HD complex? (10%) |

| IV. | IV. Consider only the HSAB characteristics in your answers
for the following questions: |
|
| V. | (a) It is suffice to say that a molecule has a mirror plane or a center of inversion can not be chiral. Comment on the above statement based on the symmetry requirement. (b) What is the conventional designation for the group of operations generated by a Sn axis when n is odd? (10%) | |
