@Kass123 Based on what you’ve posted, you will have a hard time finishing in 4 years if you attempt to double major regardless of your double major and even if you stick to chemistry/economics.
Organic chemistry 1 is tough especially if you had Weinschenk for orgo 1. It also sounds like you’re not enjoying organic chemistry and have no particular plans that require a chemistry major. In that case, why do you want to continue majoring in chemistry? (You haven’t said you’re interested in medical school or doing chemistry research, which would require a chemistry PhD.)
There is a CS minor that you can run with your Econ major if you want the mathematical/computational rigor that goes with a CS minor. Note that a CS major requires quite a bit more than a CS major.

Have you taken any CS classes?
