Tollens' and Benedict's Test Practice Problems

Aldehydes or ketones - which can be oxidized to carboxylic acids? What tests are used to differentiate a sample of aldehyde from a sample of ketone?

Determine whether the compounds shown below will react with the following reagents: (1) Tollen's reagent; and (2) Benedict's reagent. 

i.

ii. 4-methylcyclohexanone

iii. butanal

Provide two simple chemical tests that will differentiate acetaldehyde and acetic acid.

Choose the compound/s that will yield a positive result when subjected to Tollens' test. 

i. 3-methylbutanal 

ii. cyclopropanol 

iii. dimethyl ether

Identify the compound/s that will yield a positive result when subjected to Tollens' test.

i. 4-methyl-1-pentanol

ii. 4-methyl-2-pentanone

iii. 4-methylpentanal
