They differ in that the carbonyl carbon in ketones is bound to two carbon atoms (RCOR’) while that in aldehydes is bound to at least one hydrogen (H2CO and RCHO) Thus aldehydes always place the carbonyl group on a terminal (end) carbon while the carbonyl group in ketones is always internal |

What is the difference between aldehydes and ketones?
- Aldehydes have at least one hydrogen atom bonded to the carbonyl group, theother group may be either a hydrogen or an alkyl (or aryl) group. In ketones,the carbonyl group is bonded to two alkyl or aryl groups. The two groupsbonded to a ketone may be similar or different resulting in a symmetrical oran unsymmatrical ketone, respectively.
Do aldehydes and ketones undergo nucleophilic addition reactions?
- Since aldehydes and ketones both possess the carbonyl functionalgroup, they undergo similar chemical reactions. Contrary to electrophilic addition reactions observed in alkenes, thealdehydes and ketones undergo nucleophilic addition reactions.
Which reaction gives acetaldehyde and ketone?
- By ozonolysis of alkenes: As we know, ozonolysis of alkenesfollowed by reaction with zinc dust and water gives aldehydes,ketones or a mixture of both depending on the substitutionpattern of the alkene (Unit 9, Class XI). By hydration of alkynes: Addition of water to ethyne in thepresence of H2SO4 and HgSO4 gives acetaldehyde.
How are aldehydes oxidised to carboxylic acids?
- Aldehydes are easilyoxidised to carboxylic acids by mild oxidising reagents such as Tollens’ reagent andFehling’s reagent. These oxidation reactions are used to distinguish aldehydes fromketones.

Aldehydes and ketones are hydrogen bond acceptors; this makes them have considerable solubilities in water Ketones such as acetone are good solvents because they dissolve both aqueous and organic compounds Recall that acetone is a polar, aprotic solvent Reactions with acids: – The carbonyl oxygen is weakly basic |
|
Aldehydes and Ketones
Because of the polarity of the carbonyl group, aldehydes and ketones are polar com- pounds and interact in the liquid state by dipole–dipole interactions As a result, aldehydes and ketones have higher boiling points than those of nonpolar compounds with compa- rable molecular weight |
