6. [1pt] When you treated the reaction TLC with 2,4-dinitrophenylhydrazine solution, you must have observed that the starting materials show up as bright orange spots instantaneously, whereas the product either shows no change or appears as a faint spot. Explain this observation. 8. [1 pt] 4-chlorobenzaldehyde and 4-bromoacetophenone are both solid starting materials for the synthesis of substituted chalcone. When both of...

7. [3 points] Discuss a) why is dimethylaniline chosen for this experiment (methyl orange synthesis) instead of aniline? (Keywords = Activating/Electron Donating Groups) NH b) Draw a potential by-product of using aniline in this reaction. (Hint = It occurs before the EAS mechanism). Describe it using few sentences.

QUESTION REVIEW Question 6 Status: Not yet answered I Points possible: 1.00 Aspirin synthesis involves the addition of an acetyl group to salicylic acid in a condensation reaction with an alcohol. The acety group could be added with a carboxylic acid but the preferred procedure is to use the acid anhydride. Why is preferable to use an acid anhydride for ester formation with an alcohol rather than a carboxylic acid? Select one: ОО Acid anhydrides are less stable than esters...

Multistep Synthesis: Synthesis of Amine (Organic Chemistry
Lab)
Question
1. Explain each step of reaction mechanism. (How does it
work?)
2. Discuss reason for reaction sequence. (Why must one reaction
occur before another?)
3. Explain how IR supports the major product.
Experiment Procedure
Imine Formation:
Weigh a 20 mL beaker and then add 380 mg of ortho-vanillin and
268 mg of para-toluidine. Care should be taken to add equivalent
molar amounts of the two reactants.
Observe the mixture and record...
