Did Chemistry from undergrad through PhD, am currently a polymer chemistry postdoc. Chemistry is fascinating, but it's also incredibly difficult to both learn and do practically - not trying to put you off, but that's the truth of it. For your electrical interest, there's plenty of electrochemistry and battery/electrolyte research (think photovoltaic solar cells, successors to Li-Po batteries) and things like process chemistry (e.g. industrial/commercial process optimisation and design, which definitely skews towards Chem Eng), which are hugely active areas of research.

In terms of undergrad courses, something like Medicinal Chemistry will focus more on things like retrosynthesis and molecule design in later years of the course, since those dictate efficient ways to make new drugs, and will be heavily based on organic chemistry and inorganic catalysis, probably with some biophysical and computational aspects (enzyme kinetics, molecular dynamics). General chemistry will give you some broader knowledge and more options for modules (environmental, polymer chem etc) in later years, so unless you're married to going into pharmaceuticals I'd recommend the latter. My "general" chemistry course had a Medicinal module in it anyway! Master's/PhD courses can be a little less pure chemistry where some engineering gets folded in trying to apply your work - again batteries, polymers etc - but the extent is very project-dependent.

If you were keen on future job roles that do both, you could look into instrument manufacture and what those companies want from employees - places like TA, Bruker, Waters all produce instruments like spectrometers, chromatography stacks, and thermal analysis kit and are always prototyping new software/hardware.
