To distinguish:
Between
Introduction:
Nonpolar molecules are hydrophobic because they usually lack the ability (intermolecular forces) to interact with water molecules. They usually lack the ability to form hydrogen bonds, ionic bonds, or have any sort of dipole interaction with water. Since they cannot interact with water molecules on a molecular level, they tend to stay by other nonpolar molecules (molecules which they can interact with, hence oil and water do not mix very well or at all).
b.
To distinguish:
Between ionic interactions and polar interactions.

- A 100mM lactic acid/lactate buffer was found to have a lactate to lactic acid ratio of 2 and a pH of 4.2. What is the pKa of lactic acid? Can you please help show the calculations?arrow_forwardUsing line angle formulas, draw thestructures of and name four alkanes that have total of 7carbons, one of which is tertiary.Please explain this in detail and can you also explain how to approach a similar problem like this as well?arrow_forwardUsing dashed line wedge projections drawthe indicated compounds and indicate whether thecompound you have drawn is R or S.(a) The two enantiomers of 2-chlorobutane. Can you please explain your steps and how you would approach a similar problem. Thank you!arrow_forward

I have a 500 Hz H-NMR for 1,5-bis-(4-methoxyphenyl)-penta-1,4-dien-3-one. I need to label the signals with the corresponding H's. Then, find out if the two alkenes are cis or trans by calculating the J values. I believe that I have the H-NMR labeled correctly, but not sure if I got the J values correct to determine if the two alkenes in the compound will make the compound cis or trans.arrow_forwardWhat is the only possible H-Sb-H bond angle in SbH3?arrow_forward
