Attach a pipet to a syringe and measure 0 8 mL of the aldehyde into a 25 mL Erlenmeyer flask Replace the pipet and add 0 2 mL of the ketone to the flask followed by 4 mL of ethanol and 3 mL of 2 M sodium hydroxide solution Swirl the contents of the flask frequently for at least 15 minutes
Organic Chemistry 4 Aldehydes and Ketones Both aldehydes and ketones have a carbonyl C=O group (carbon double bonded to an oxygen) Aldehydes have the carbonyl at the end of a chain while ketones have a carbonyl between carbon atoms in the middle of a chain
Because the carbonyl group is present in both aldehydes and ketones the two classes often react similarly With the same reagent aldehydes usually react faster than ketones mainly because there is less crowding at the carbonyl carbon Aldehydes are also more easily oxidized than ketones
share the carbonyl group aldehydes and ketones share much of their chemistry but they are different enough to be considered different classes of compounds This situation is similar to that of alcohols and phenols which both share the -OH group Aldehydes and ketones both undergo a reaction type known as nucleophilic addition

What is the chemistry of aldehydes and ketones?
The chemistry of aldehydes and ketones is characterized by the versatile reactivity of the carbonyl group. In this experiment, you and a partner will be given an unknown aldehyde and an unknown ketone, and you will determine their identities by performing several chemical reactions. Oxidation by chromic acid
How do you measure aldehyde?
Attach a pipet to a syringe and measure 0.8 mL of the aldehyde into a 25 mL Erlenmeyer flask. Replace the pipet and add 0.2 mL of the ketone to the flask followed by 4 mL of ethanol and 3 mL of 2 M sodium hydroxide solution. Swirl the contents of the flask frequently for at least 15 minutes.
What is a positive aldehyde test?
A positive test for an aldehyde will be a silver mirror formed on the test tube if the test tube was clean; if the test tube was not clean, a black precipitate will form. Record your results on the report sheet. Clean the test tubes with 1 M nitric acid.
How do you balance hydrocarbons in chemistry?
You may use the molecular formula for the organic compounds to make the balancing easier. Remember that the product of the combustion of a hydrocarbon is carbon dioxide and water.
