Question

T or F

1. C5H12O can be either an aldehyde or a ketone

2. A positive Tollens' test is the appearance of a silver mirrow on the inner walls of a test tube.

3. Aldehydes and ketones have lower boiling points than alcohols of comparable molar mass because they do not undergo hydrogen bonding.

4. The reduction of a six carbon aldehyde will give a six carbon primary alcohol.

5. Pentanal and 2-pentanone are isomers.

6. 2-Pentanone and 3-pentanone are isomers

7. The functional group of aldehydes and ketons is called a carbonyl group.

8. Aldehydes can be oxidized to carboxylic acids.

9. Aldehydes can be reduced to secondary alcohols.

1.False ( because both aldehyde and ketone have a general formula of CnH2nO , the given compound is alcohol or ether)

2.True ( tollens test is often called silver mirror test, due to this reason)

3.True ( aldehyde and ketone doesn't undergo hydrogen bonding)

4. True ( aldehydes are reduced to primary alcohol)

5. True ( they are functional isomers)

6.True ( they are metamers)

7.True ( functional group present in both aldehyde and ketone is C= O carbonyl group)

8.True ( aldehydes are oxidised to carboxylic acid)

9.False ( aldehydes are reduced to primary alcohol)
