a) Draw all of the products obtained from the base-catalyzed aldol condensation reaction between butanal and pentanal(crossed and self) b) Show the half reaction corresponding to the reduction of permanganate ion to manganese dioxide. Show the half reaction corresponding to the oxidation of cyclopentene to 1,2 dihydroxycyclopentane. Add the two half-reactions together to give the overall net ionic equation of the oxidation of cyclopentene to 1,2 dihydroxycyclopentane using permanganate ion. Can anyone help me out?
