Review Quiz #8

Comment: Provide ALL correct answers for each problem.

The quizzes become increasingly more interesting. This quiz should take you about 20 minutes if you have good preparation. If you have difficulty with these topics, we STRONGLY recommend that you review the videos that we have listed.

Please remember, you are allowed a calculator AND a periodic table!

1. According to the reaction equation below, what weight of CH3CH2Cl  is needed to produce 2.00 g of CH3CH2OCH2CH3?
(Atomic weights: C = 12, O = 16, H = 1, Na = 23, Cl = 35.5)

CH3CH2ONa + CH3CH2Cl –> CH3CH2OCH2CH3 + NaCl

 
 
 
 
 

2. What type of reaction is shown below?

CH3CH2ONa + CH3CH2Cl —> CH3CH2OCH2CH3 + NaCl

 
 
 
 
 

3. A transformation is performed with 2 mmol each of CH3CH2NH2 and CH3C(=O)Cl according to the following reaction:

CH3CH2NH2 + CH3C(=O)Cl —> CH3CH2NHC(=O)CH3 + HCl

What is the theoretical yield of CH3CH2NHC(=O)CH3 in this reaction (e.g. the theoretical yield assumes complete conversion to the product)?
(Atomic weights: C = 12, O = 16, H = 1, N = 14, Cl = 35.5)

 
 
 
 
 

4. A reaction in which some chemical bonds are broken and some are formed, but the product has all of the same atoms as the starting molecule is:

 
 
 
 
 

5. What type of reaction is shown below?

CH3CH2Cl + NaH —> CH2=CH2 + NaCl
