Hi Anshika,
Mathematics will be there as a subject in B.Sc. General but not in B.Sc. Chemistry Hons. But in B.Sc. Chemistry Hons. you will be required to have a good knowledge of Mathematics as you will be required to solve many questions using your mathematical ability. If you hate Mathematics than you can go for B.Sc. Chemistry Hons. but you will not be able to learn Maths there you will have to apply what you have learnt. If you want to learn some Maths and then do calculations easily then you can go for B.Sc. General.
As per my advice, you should go for General B.Sc. as you will get to learn some Maths and then solve questions using your mathematical ability.
Feel free to ask doubts in the Comment Section.
I hope this information helps you.
Good Luck!
