    Organic retrosynthesis

    Please show us what you have worked out so far.

    Sn1/sn2

    Can the aromatic ring stabilize a putative carbocation (assuming it goes SN1)? A drawing may be helpful.
  3. My working hypothesis is that each protein might be expressed in slightly different amounts. Each ribosome binding site might be different, for example. However, I have only done a little reading on this subject.

    Chemical reactions

    Your structure of ethylenediamine is incorrect. Remember the Lewis octet rule.

    Amide Reaction

    What do you mean by placement of the N, and why do you think it might be important?

    Diphenyl ether formation

    @OP, The Williamson ether synthesis is usually given as an example of SN2 chemistry in introductory organic chemistry. Aryl bromides or aryl iodides are unreactive in SN2 reactions. Why do you suppose that is the case?

    Diphenyl ether formation

    My understanding of the Ullmann reaction is limited, but it appears to be a way to make biaryl compounds. Relative to what you want, the product is missing the oxygen. Can you explain why you think that the Williamson synthesis might not work in this instance?

    Phenacetin

    What do you think? Suppose you compare it to acetaminophen. What is different?

    TLC and polarity

    I would also consider the interaction between the solvent and the silica (the stationary phase).

    The synthesis of aspartame

    It is often helpful to think in terms of nucleophiles and leaving groups.
  11. Can you think of something that might precipate under these conditions?

    Lauric Acid Buffer Help!!!

    it is very unusual to make buffers up in anything but aqueous media. I don't know what the solubility of lauric acid is in ethanol, but whatever its pKa in water is, it will have a different pKa i ethanol.

    Questions about hylauronic acid

    What is BDDE?

    Interpretive spectroscopy

    Chemical shifts can be estimated on the basis of which phosphorus-containing functional group is present. The term "predict" may also imply that one provide the multiplicity. Can you show us your work so far?
  15. Do you know which amino acid residues absorb UV light? That would be how I would start my research into this topic.
