Answer:
Aldehyde has C=O bonded to atleast one H atom while Ketone has C=O bonded to two carbon atoms
Aldehyde - galactose, glucose, glyceraldehyde, fructose
Ketone - Trioses, Tetroses, Pentoses, Hexoses
Explanation:
Similarity
Both the aldehyde and ketone have C=O group
Difference
In aldehye the C=O group require atleast one hydrogen atom or the functional group in aldehyde is -CHO
while in ketone the function group is C=O only that is bonded to two carbon atoms.
Example
Aldehyde - galactose, glucose, glyceraldehyde, fructose
Ketone - Trioses, Tetroses, Pentoses, Hexoses
