Question
Chapter 21, Problem 1DE
Interpretation Introduction
To determine: If the alanine (amino acid) to be more soluble in water or hexane.
Expert Solution & Answer
Answer to Problem 1DE
Solution: Alanine (amino acid) is more soluble in water.
Explanation of Solution
Solubility of any solute in a solvent depends upon the solute-solvent interaction. Greater the solute-solvent interaction, greater will be the solubility.
Alanine (amino acid) is a polar compound containing
As the strength of hydrogen bonding is greater than dispersion forces. The solute-solvent interaction in solution of alanine in water is greater than that of solution of alanine in hexane. Hence, alanine (amino acid) is more soluble in water.
Conclusion
Alanine (amino acid) is more soluble in water because the solute-solvent interaction in the solution of alanine in water is greater than the solution of alanine in hexane.

Which carbocation is more stable?
Are the products of the given reaction correct? Why or why not?
The question below asks why the products shown are NOT the correct products. I asked this already, and the person explained why those are the correct products, as opposed to what we would think should be the correct products. That's the opposite of what the question was asking. Why are they not the correct products? A reaction mechanism for how we arrive at the correct products is requested ("using key intermediates"). In other words, why is HCl added to the terminal alkene rather than the internal alkene?
