Sep 7 2014 · Physical Properties Aldehydes and ketones are polar because they contain a carbonyl group (oxygen is very electronegative compared to carbon) Aldehydes and ketones can form hydrogen bonds with water so small aldehydes and ketones are water-soluble However they cannot form hydrogen bonds to each other so their boiling points are not very high |

Experiment – Identification of Aldehydes and Ketones
Aldehydes are oxidized by chromic acid ketones are not When an aldehyde is oxidized by orange-brown chromic acid the chromic acid is reduced to Cr+3 which is green Consequently chromic acid can distinguish between aldehydes and ketones It is also true that other functional groups primary and secondary alcohols for example |

Aldehydes and ketones behave differently toward oxidizing agents Because aldehydes have a hydrogen atom directly bonded to the carbonyl carbon it makes them more reactive to oxidation than ketones R O H [O] strong oxidizing agent R O OH aldehyde carboxylic acid Ketones which have no hydrogen attached to the carbonyl carbon atom may be |
What are the properties of aldehydes and ketones?
- Properties of Aldehydes and Ketones Aldehydes and ketones have lower boiling points than analogous alcohols (Table 1), and are less soluble in water than alcohols; this is to be expected as they do not contain OH groups and so do not participate in hydrogen bonding.
How to analyze an unknown aldehyde or ketone?
- In this experiment, you will analyze an unknown aldehyde or ketone by performing classification tests, by measuring the refractive index and boiling point, and by preparing a derivative and measuring its melting point. You will identify your unknown by comparing its data with literature values.
What is the reaction between acetaldehyde and methyl ketones?
- Acetaldehyde and methyl ketones, with groups CH3 – C=O, produce the equivalent haloform when treated using halogen or alkali. It would be referred to as the Haloform response. A carbon atom connected with carbonyl carbon was known as – carbon, and the hydrogen atom is known as – hydrogen.
What is B-hydroxy aldehyde or ketone?
- Under the influence of dilute base or dilute acid, two molecules of an aldehyde or ketone may combine to form a b-hydroxy aldehyde or ketone. The a-carbanion generated by the base from one molecule of ald.
