3. Draw all the aldol addition products that are formed when a mixture of acetaldehyde and pentanal is treated with aqueous sodium hydroxide. 4. A reaction, such as described in question 3, which produces a mixture of products is generally not useful for organic synthesis. Suggest a change in the reaction starting materials for question 3 that would produce a single, similar product. 5. Draw a generic mechanism for aldol condensation. 6. The last step for an aldol condensation involves...
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?
