Hello Maimuna,
If you want to pursue your career in Chemistry that's really good. To do so you can do in both ways like if you want to do research or want to be a professor than you can do B.Sc in Chemistry after that M.Sc followed by P.Hd in the field of your preference.
Also, you can do B.Tech in Chemical engineering it also somewhat related to chemistry. After doing that you can go for masters thereafter PhD and research in the field of your choice.
Hope this will help you. Feel free to ask any query.
