1. why is the cannizzaro reaction limited to aldehydes having no alpha hydrogen atoms? 2. why do ketones having no alpha hydrogen atoms not undergo the Cannizzaro reaction?
what would happen to the flow of carbon in central metabolism if alpha-ketoglutarate was being removed to make the amino acid glutamate?
Explain why enol tautomerism is NOT possible when there is no alpha hydrogen present.

For C i think my professor is trying to say that NaOH deprotonates the alpha hydrogen that produces either the thermodynamic or kinetic product, and the hydrogen being deprotonated has a box around it. I thought that NaOH protonates the thermodynamic product, but wouldnt the product of this deprotomation be the kinetic product, as a resonance form of the enate anon produces would contain a monosubbed double bond whereas deprotonatoning the orher alpha hydrogen would lead to a resonance form...

A hydrogen ion which has had its electron removed and an iron ion which has had one electron added are brought near each other. Which best describes the electrostatic forces on these ions? A. The ions attract with the iron ion experiencing a greater force. B. The ions attract with the hydrogen ion experiencing a greater force. C. The ions attract with equal magnitude forces. D. The ions repel with the hydrogen ion experiencing a greater force. E. The ions...
22. Consider an alpha helix with sequence VLADWMAVELA, and consider the hydrogen bonds that are required in order to form the alpha helix. A. Fill in all of the hydrogen bonds that must form between a given residue's backbone N-H backbone C-O, or R group, indicating what the hydrogen bonding partner for each will be. For example, the C-O of V1 is a hydrogen bond acceptor of the W5 N-H hydrogen bond donor, reflected in the appropriate squares under V1...
