There are so many! -Does anyone have a trick to memorizing the solubility rules? -Gen Chem, Quantum Mechanics - how much detail to we need to know? -Org. Chem, Meta, Para, Ortho Directors - are there common ones we should know? ...Clearly trying not to fill my brain with aimless info! ... Thanks in advance!!
