Dear Student,

Forensic science involves the study of scientific applications and applying scientific knowledge during the investigation of the crime.

The relation is that you have to use the chemistry while investigation that by which chemical crime is done example-analyze blood, DNA etc  which is the study of forensic science.Basically,it covers various fields chemistry,biology,geology,physics,psycology  etc

You can do masters in  forensic science after bsc in chemistry which is good option or you can also do the bsc in forensic science

Thanks
