If it's about Organic Chemistry, then I will suggest :
Find any product in the market which appeals you, for example, anti-mosquito liquid, floor cleaner, any aromatic liquid used for different purpose, any nasal spray etc.
Try to make exactly same product with its side effects, if any, removed through your research. It is called 'Applied Chemistry'.
For example, there can be 'anti-mosquito' spray which is completely natural, but not so effective, but a spray can be developed which can be natural with some added organic chemicals and with increased effectiveness. This kind of research will help you a lot in future.
Tell me your opinion about it. Best of luck!
