ethanol + maleic anhydride is this suitable for recrystallisation or does esterfication occur when ethanol is...
Would either ethanol or chloroform be suitable for recrystallising naphthalene or maleic anhydride - if so which and why?
All of the following would be suitable reaction partners in a Diels-Alder reaction with maleic anhydride EXCEPT A. acyclic 1,3-diene B. cyclic 1,3-diene C. acyclic 1,4-diene D. alkyl-substituted acyclic 1,3-diene please help asap!! Thank you
why should the maleic anhydride bottles be kept tightly closed when not in use? And then explain by the equaion.
Draw a structure for the exo product formed by cyclopentadiene and maleic anhydride. Because the exo form is more stable than the endo form, why is the endo product formed almost exclusively in this reaction? In addition to the main product, what are two side reactions that could occur in the preparation of cis-Norbornene-5,6-endo-dicarboxylic anhydride from cyclopentadiene and maleic acid in the presence of ethyl acetate and ligroin?

Draw a structure for the exo product formed by cyclopentadiene and maleic anhydride. Because the exo form is more stable than the endo form, why is the endo product formed almost exclusively in this reaction? In addition to the main product, what are two side reactions that could occur in this experiment? The infrared spectrum of the adduct is given in this experiment. Interpret the principal peaks.
- vivUINUAR 3) Why is cyclopentadiene more reactive ntadiene more reactive with maleic anhydride than with itself? chiral centers does endo-norbornene-cis-5,6-dicarboxylic acid possess? Is the 4) How many chiral centers does endo molecule itself chiral? (continued) 5) Endo-norbornene-cis-5,6-dicarboxylic acid can be converted back into its anhydride precursor by treatment with anhydrous acid. Propose a mechanism for this reaction.
Predict the two most likely mechanisms which occur when 2-iodohexane is heated in ethanol. SN2 and E2 SN2 and SN1 E2 and SN1 E1 and E2 E1 and SN1
4. Explain why maleic anhydride is exceptionally reactive and why anthracene is usually unreactive. Explain why did this Diels-Alder reaction proceed? Why does anthracene react from the central ring system and not one of the outer rings?
Reaction is Diels-Alder Reaction: 0.6 g (Anthracene) + 0.3 g (maleic anhydride) --> product [9,10-dihydroanthreceno-9,10-endo- α, β-succinic anhydride] 0.70 grams obtained. When vacuumed, xylened and isolated, the product yielded 0.70 grams product. Please show how to calculate % yield with the weights above (Theoretical + Actual).
5. (a) compare the carbonyl region of your IR spectrum with
that of maleic anhydride. What are the similarities? what are the
differences?
(b) Does your IR spectrum allow you to confirm that the
structure of the product is a combination of the two reactants?
Briefly explain.
