(D) Another repeating transformation is the reductive amination that shows up in the Schemes 3, 5 and 6. This takes Ar-NH₂ to Ar-N(CH3)2 with NaBH4/HCHO (formaldedyde). This provides the "rear" dipole that drives the nanocar. Show the mechanism for converting Ar-NH₂ → Ar-N(CH3)2 with two formaldehyde molecules and NaBH4. You will need to review your notes from lab5 in

organolithium reagents are strong bases. Because of this, they cannot be prepared from compounds that contain acidic groups (-OH, -NH:, -NHR, -SH, -C=CH, RCO:H) or compounds that have carbonyl groups.

A special case of alcohol dehydration is a reaction called the pinacol rearrangement. A molecule called pinacol, a diol (a molecule with two OH groups) is heated in the presence of sulfuric acid. The mechanistic steps are the same as you have seen for alcohol dehydration. The product, pínacolone, features a new C-O bond rather than the new C-Cл bond that is usually formed in alcohol dehydration. 1st attempt tox AN → i H-O 1 See Periodic Table See Hint 1

Because phenol (C6H5OH) is less acidic than a carboxylic acid, it can be deprotonated by NaOH but not by the weaker base NaHCO3. Using this information, write out an extraction sequence that can be used to separate C6H5OH, benzoic acid, and cyclohexanol. Show what compound is present in each layer at each stage of the process, and if it is present in its neutral or ionic form.
