AlDEhyDES AND KEtONES
Aldehydes and ketones are oxidation products of the alcohols. Each of these types of compounds contains the carbonyl group. Since both aldehydes and ketones are carbonyl compounds, it is not surprising that their reactions are similar. Often the only difference is in the rate of their reactions, ketone reactions being slower.

the name aldehyde is contraction of the term “alcohol dehydrogenation”, indicating that two hydrogen atoms are removed from an end carbon when aldehydes are prepared from primary alcohols. With the exception of formaldehyde, R in the general formula R-ChO can be any alkyl group. In formaldehyde, hChO, R is an h atom. the general formula shows that the aldehydes differ from their parent hydrocarbon molecules in that the two hydrogen atoms on the end carbon have been replaced by a single oxygen atom with a double bond to a primary carbon atom.
