what are aldehydes oxidised to

carboxylic acids

1 of 6

write the equation of reducing butanone to button-2-ol

CH3CH2COCH3 +2[H] -> CH3CH2CH(OH)CH3

2 of 6

write the equation of reducing propanol with KCN

CH3CH2CH0 + (H+) + (-CN) -> CH3CH2CH(OH)CN

3 of 6

where does the H+ ion come from in reduction of aldehydes and ketones?

from the acid solvent

4 of 6

what are the test tube tests for aldehydes and ketones

tollens reagent and fehlings solution test

5 of 6

why can nucleophilic addition to aldehydes and asymmetric ketones result in racemic mixtures?

the bonding about a C=O group is an aldehyde and ketone is planar. this means there is 50:50 chance of the nucleophile attacking from one side of the molecule or the other this results in equal proportions of each optical isomer forming and so a rac
