Calculting in Chemistry
Calculting in Chemistry
(A.) Calculate the cost per gram (g) of synthetic baccatin III, the Taxol precursor, using the following assumptions. Basically, what you are doing here is calculating how much it would cost to just synthesize the chemical needed to make Taxol in the laboratory, without relying on nature. Be sure to look at the attached picture (Figure 1) before trying to answer this question. You d

What is a Polar Covalent Bond?
What is a Polar Covalent Bond?
A polar covalent bond is a bond between two non-metals with different electronegativities. Only bonds between the same elements are truly nonpolar. The higher the difference in electronegativity, the more polar the bond is. Take a look at this table of electronegavities and let's try some examples.

Chemistry question on enantiomers
Chemistry question on enantiomers
So this is actually a question in my biology class but it is a question about enantiomers so I figured I'd put it in Chemistry. Anyway! So the answer is A being that A is NOT an enantiomer. I'm not understanding why it's not if D is the same thing just with CH3 instead of a H. Any help is appreciated.
