In general, for this kind of problem first you have to look at the molecular geometry. Then you have to apply all sorts of symmetry operations to identify the point group. A great deal of visualization is involved in the process.

(a)

allyl tricarbonyl cobalt complex

[See pages 69-70 of the book titled "Molecular Symmetry" by David Willock in google books. It gives a general guideline and flow diagram on how to assign point groups. Also the attached lecture notes show how to determine proper rotation axis, mirror plane, center of symmetry ...

Solution Summary

This solution comprehensively discusses the background and rationale behind the problem with the help of some diagrams and gradually arrives to the answers.
