What is the problem of attempting an Adols condensation using different aldehydes
What determines whether a group on a benzene ring will be activating or deactivating and ortho para
When iron chloride FeCl3 is dissolved in water the solution becomes acidic. The preparation of the Fe(NO3)3 solution and the KSCN solution used 0.5 M HNO3 as the solvent instead of water. Explain why this was done. Hint: Consider Le Chatelier's Pr..
