Organic chemistry post-lab question: "Why is important
to add the alkyl halide dropwise in your reaction? (Hint: your
reaction is not heated, but you still need a water-cooled
condenser!)" Please answer in detail!

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...

Pre-Lab Assignment
1) Draw the reaction mechanism for the reaction.
2) Determine the limiting reagent.
Procedure 1 Place approximately 1 g of stilbene dibromide prepared in last week's experiment in a 50 mL round bottom flask. Record the exact mass. Add 0.8 g of KOH and 4 mL of triethylene glycol from the syringe provided in the fume hood (rinse any crystals from the sides of the flask while adding triethylene glycol). 2 Heat the stirred reaction mixture to a...

Prelab questions:1. Make sure the reaction table described above is completed in your notebook.2. Two benzaldehyde molecules combine with one acetone molecule in this aldol reaction. If someone uses 5.0 mL of benzaldehyde and 2.5 mL of acetone to try to improve the yield of product, is this the correct ratio of molecules so that there is no excess? Why or why not?The Aldol Reaction: Synthesis of DibenzalacetonePurpose: Introduce the student to the hands-on chemistry of carbonyl condensations.Warning: Dispose of...
