Homework Answers
no you can't use ethanol
minimum criterial is that solvent should not soluble in milk and fat should soluble in that solvent
ethanol is a hydrophilic solvent it will easily soluble in methanol but that should not happend

hypothesize why a tertiary alcohol is a good solvent for an sn2 reaction where CsF is the nucleophile and iodide is the leaving group there are various electrophiles that iodide is leaving from who's identities don't seem to matter. from everything I've learned up to now protic solvents are NOT good solvents for sn2 rxns. there have been numerous articles on a research project where 18F is being used for radiolabeling in biological systems and they used tert-amy-alcohol for the...

Extraction Q1. Why doesn’t the neutral organic compound dissolve in the 1.5 M NaOH solution? Q2. Why is diethyl ether a good choice for the organic solvent in this extraction experiment? Q3. What experimental difficulty would you encounter if you neglected to include the drying step before evaporating the ether solution of the neutral organic compound? Q4. Why are the two organic compounds recrystallized before their melting points are determined? Q5. What IR bands are most useful in distinguishing a...

explain why casein precipitates (curdles) when acetic acid is added to your milk mixture. What is the function of acetic acid. 5. This precipitation can also be achieved through bacterial fermentation (e.g., spoiled milk). Explain what is happening during this process. 6. A third method of curdling milk is by adding the enzyme rennin (chymosin). Most cheeses are made this way. Do some online research and explain how this protease enzyme works and why milk curdles when it's added. 7....
