how to make Pentonic acid into 2-Pentanone?
can someone help me figure out how to draw these please 3-methylbutan 4-methyl-2-pentanone propanoic acid ethylpropanoate dimethylethanamide
Draw the mechanism and the product(s)for the acid-catalyzed reaction of (S)-4-chloro 2-pentanone with 2 moles of methanol; indicate which is the hemiacetal and the acetal structures. Consider how would the mechanism and the product be different if the same ketone underwent acid hydrolysis in the absence of methanol? Also, consider the reversibility of the above mechanisms.
40 60 100 120 140 160 2. Two mass spectra are shown below. One is that of 2-pentanone and the other is of 3- pentanone. Which is which? Show how you made your decision. 3-pentanone to 40 60 80 100 120 140 160 60 80 100 120 20 40 140 160
so 9 CHỊCH,CH,CH,CHN + CHỊCH,MgBr, then Hạ 1.) LIOH 2.) оны 3.)H20 2.) (a) With 3-pentanone, use acid catalysis (using reagents of your choice) to produce a hemiacetal. Show the arrow-pushing mechanism. (b) Show what happens when we run this reaction for an even longer amount of time (still, use arrow- pushing). 3.) (a) Using an arrow-pushing mechanism, demonstrate how 3-pentanone reacts with H;SOJHO (b) Demonstrate with an arrow-pushing mechanism how 3-pentanone reacts with NaOH/H2O. OCH2CH3 HOW? H3CH2CH.. -CH₂CH₃ H3CH2CO
choose a starting material (4-methyl-2-pentanone, 2-methyl-3-pentanone, 2,3-dimethylbutanal) and a reagent from A-F to synthesize 2,2-dimethoxy-4-methylpentane. Choose a starting material and a reagent (A-F) to synthesize the given product. When [Select ] is treated with (Select ] it will produce 2,2-dimethoxy-4- methylpentane. REAGENTS C. A.
