Answer:
C. The criterion of minimizing chemical waste favors the use of organic solvents.
Explanation:
I chose B on my quiz and got it wrong, then it showed that C was the correct answer. I didn't know this one myself.
D. It is the heat required to change a gram of substance from a liquid to a gas.
Explanation:
The heat of vaporization is the heat required to change a gram of substance from a liquid to a gas.
- It is also known as the enthalpy of vaporization.
- The heat of vaporization is the quantity of heat needed to change one gram of a substance from liquid to gas.
- This heat of vaporization is dependent on the pressure conditions the process is taking place.
- Different liquids have their heat of vaporization.

Answer:
hex-1-ene with a hydroboration-oxidation reaction
Explanation:
In this case, we can start with the structure of 1-hexanol. In this alcohol, the <u>"OH" is on the first carbon</u>. Thus, the alkene that this alcohol can produce must have a double bond between carbons 1 and 2, that is, <u>hex-1-ene</u>.
Now, it is important to know which of the reactions we can use, <em>hydroboration-oxidation, </em>or <em>oxymercuration-reduction</em>. To decide which reaction to using, we must look again at the alcohol we want to produce. In this alcohol, the "OH" is attached to a primary carbon. Therefore, the addition of the "OH" must be made on the <u>least substituted carbon</u>, that is, carbon number 1.
Because of this, an <u>anti-Markovnikov reaction</u> (a reaction in which the "OH" is added on the less substituted carbon) must be used. The reaction, which serves us then is: <u>hydroboration-oxidation</u> since this reaction is anti-markovnikov.
