Usage of fragrance, smell and odour

[Masaniparesh]

Could any one give me some examples where

1. each of these words fit properly
2. we can not replace these words in place of each other. i.e we have to use smell and we cannot use fragrance or odour.

Thanks,
Paresh

The pedophile was in bad odor with all his neighbors.
