13. Alcohols and Carbonyl Compounds

Fill in the missing reactant, reagent, or product for each of the following oxidation reactions. react similarly to chromic acid

(d)

Fill in the missing reactant, reagent, or product for each of the following oxidation reactions.

(a)

In Hinkley, the cleanup continues today. In one process PG&E is using to mitigate the chromium(VI) toxicity, ethanol is injected into the soil. How would this reduce the chromium(VI) contamination?

What is the major product(s) of each of the following reactions?

h.

Predict the product of the following reactions.

(b)

Identify the alcohols that would undergo oxidation to produce the following carbonyl compounds.

(c)

Predict the product of the oxidation reactions shown.

(a)

If there is no water present, the hydrate of an aldehyde cannot form. Could an aldehyde itself (not the hydrate) be oxidized to a carboxylic acid? Why?

In light of Figure 24.22, provide a mechanism by which para-dihydroxybenzene is oxidized to para-quinone.

Fill in the missing reactant, reagent, or product for each of the following oxidation reactions.

(b)

Predict the product(s) that would result when molecules (a)–(p) are allowed to react under the following conditions: (ix) PCC; (x) H₂CrO₄ , H₂O. If no reaction occurs, write 'no reaction.'

(o)

Oxidation of the phenol shown gives a single quinone product. Predict this product and explain why it is the only one formed.

Fill in the missing reactant, reagent, or product for each of the following oxidation reactions.

(c)

Show how you would synthesize the following carboxylic acids, using the indicated starting materials.

(e) p-xylene → terephthalic acid
