4. The scheme below shows the reaction of a ketone, 2-propanone with methanol. :0 : : OH OH CH, - CH3 CH3 C-CH3 CH,-C-CH3 step 1 step 2 step 3 P CH,OH CH3 CH,OH step 4 OCH, - H,0 CH, Ċ–CH3 R CH;-C-CH3 step 7 step 6 step 5 ÓCH, OCH3 i) Write the missing structures (N, O, Q and R) in the above reaction scheme. ii) Name the class of compounds P and S belong to? iii) This is an acid catalyzed reaction. What does this statement mean? iv) Draw the arrow diagram in step 6 to show how intermediate R is formed? Write the equation for this step ONLY. v) Steps 3 and 7 involve loss of a proton from the intermediate ions. Why is this step necessary?
