Describe the alternative system for naming ketones. Give two examples of ketones, along with their names in both systems.

Aldehydes and ketones both contain the carbonyl group, yet the properties of these two types of compounds are different enough that they are classified separately. Without looking back at the text, draw the structures of the ketone and the aldehyde that have three carbon atoms. Name each of these compounds.

Write equations showing the oxidation of a primary alcohol and the oxidation of a secondary alcohol to produce an aldehyde and a ketone, respectively. Indicate the structure of each alcohol and of the principal organic products of the oxidations.

Mention some commercial uses of specific aldehydes and ketones .

What structural feature distinguishes aldehydes from ketones ?

What functional group is common to both aldehydes and ketones ?

Give the names and structural formulas of two other commercially important alcohols. Cite the major use of each

Write the equation for the synthesis of ethanol from ethylene. What are some commercial uses of ethanol made by this process ?

Write the equation for the fermentation of glucose to form ethanol. Why can't ethanol solutions of greater than about $13 \%$ concentration be made directly by fermentation? How can the ethanol content be increased beyond this level in beverages ?
