  c. Hydrocarbons with the same number of carbons have similar physical properties.
  d. Hydrocarbons have CC and CH dipoles that are significant.
  e. Hydrocarbons have relatively low melting points and low boiling points.



Question 2

Acetic acid can be protonated in a strong acid such as sulfuric acid. Predict which oxygen becomes
  protonated and explain why.


 

Question 3

Explain why acetic acid
 
  is a much stronger acid than ethanol.

Question 4

Using resonance structures, explain why aniline,
 
  is a weaker base than benzylamine
 

Question 5

Question 6

Complete this acid-base reaction and label the acid, base, conjugate base, and conjugate acid.
 

Question 7

Use the curved arrow method to show the electron movement and label the acid, base, conjugate acid,
  and conjugate base.


 

Question 8

Draw the conjugate acid of each species
 

Question 9

Given pKa = 15.7 for H2O and pKa = 3.2 for HF, identify the conjugate base of each of these acids and
  explain which conjugate base is stronger.

Answer to Question 1

d

Answer to Question 2

Protonation occurs on the C = O oxygen because delocalization of the charge can occur readily:

No corresponding delocalization can occur if protonation takes place on the singly bonded oxygen

because that oxygen has three sigma bonds and a lone pair and cannot accept another bond.

Answer to Question 3

The C = O group in acetic acid has an inductive effect, withdrawing electrons. More important is the
resonance effect of delocalizing the negative charge in the conjugate base of acetic acid which cannot be
done for ethanol.



Answer to Question 4

Aniline is more stabilized by resonance than its conjugate acid, but benzylamine and its conjugate acid
are equally stabilized by resonance.
