МСРВА Alkenes are oxidized to give epoxides on treatment with a peroxyacid, RCo,H, such as metachloroperoxybenzoic acid (MCPBA). Peroxyacids transfer an oxygen atom to the alkene with syn stereochemistry, i.e. both C-O bonds form on the same face of the double bond, through a single step mechanism without intermediates. The oxygen atom farthest from the carbonyl group is the one transferred. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions - XT...

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?
