Draw compounds B and C from the following reaction scheme. You do not have to consider stereochemistry. Include counter-ions, e.g., Na^+, I^- in your submission, but draw them in their own separate sketcher. Do not draw organic or inorganic by-products. Draw one structure per sketcher. Add additional sketchers using the dropdown menu in the bottom right corner. Separate products from...

Acid-catalyzed dehydration of secondary and tertiary alcohols
proceeds through an E1 mechanism. The first step is the protonation
of alcohol and oxygen to form an oxonium ion.
Dehydration of 3-methyl-2-butanol forms one major and two minor
organic products. Draw the structures, including hydrogen atoms, of
the three organic products of this reaction.
The 3.) is correct that is the minor...

Question 4 1 pts Aldol and Claisen condensations are prone to "mixed products." Which of the following techniques can be used to help reduce the mixture of products one obtains in these reactions? O Make it so that one of the reagants does not have any "alpha protons." O Slowly add any reagants which you are concerned might readily self-react...

22. Consider the following two reactions CHa(g) + 3/2。2(g) → CO2(g) + 2 H2O(g) K = 6.8 x 1 N2(g) + O2(g) → 2 NO(g) K=4.2 x 10'15 Other than the fact that they are different things reacting with oxygen to give ifferent products, what is the biggest difference between these two reactions? What does this mean about what happens...
