  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 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

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.

A good example of polar molecules can be understood when trying to make a cake. If water and oil are required, they will not mix together. If you put them into a measuring cup, the oil will rise to the top while the water remains on the bottom.

Hippocrates noted that blood separates into four differently colored liquids when removed from the body and examined: a pure red liquid mixed with white liquid material with a yellow-colored froth at the top and a black substance that settles underneath; he named these the four humors (for blood, phlegm, yellow bile, and black bile).

The B-complex vitamins and vitamin C are not stored in the body and must be replaced each day.

Did you know?

Patients should never assume they are being given the appropriate drugs. They should make sure they know which drugs are being prescribed, and always double-check that the drugs received match the prescription.

Did you know?

The human body's pharmacokinetics are quite varied. Our hair holds onto drugs longer than our urine, blood, or saliva. For example, alcohol can be detected in the hair for up to 90 days after it was consumed. The same is true for marijuana, cocaine, ecstasy, heroin, methamphetamine, and nicotine.
