Question
Ethanol (CH3CH2OH) is an example of a compound with an alcohol group. Alcohols can act as acids or bases in
solution. We can consider a reaction of ethanol with NaOH to see the acid/base properties.
a. Draw Lewis structures of ethanol and sodium hydroxide. Be sure to show all lone pairs and formal charges.
ethanol
sodium hydroxide
b. Draw out a full equilibrium acid/base reaction between ethanol and sodium hydroxide, showing the
correct arrows for electron movement.
Use the pka table at the right to answer the following questions.
C. What would you expect the equilibrium composition of this reaction to
be?
d. If a chemist wanted to push the reaction to create a high yield of product,
what would be a good base to use?
