Identification of Aldehydes and Ketones
Aldehydes and ketones differ from alcohols in having two less hydrogen atoms. 1° alcohol oxidation aldehyde;. 2° alcohol oxidation ketone.

ALDEHYDES AND KETONES 5 1 Introduction H Aldehydes have a -C=O functional group An aldehyde requires that at least one of the bonds on the C=O group is a hydrogen atom When the carbonyl group (C=O) has two C atoms bonded to it is classified as a ketone 5 2 Naming Aldehydes and Ketones Systematic: methanal ethanal propanal butanal

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

Identification of an Unknown Aldehyde or Ketone Background Structures of unknown compounds can be determined by comparing physical properties performing functional group tests and checking melting points of derivatives against those of known compounds reported in the literature
What is the difference between aldehyde and ketone?
- 5.1 Introduction H Aldehydes have a -C=O functional group. An aldehyde requires that at least one of the bonds on the C=O group is a hydrogen atom. When the carbonyl group (C=O) has two C atoms bonded to it is classified as a ketone. 5.2 Naming Aldehydes and Ketones
What is the functional group of an aldehyde?
- H Aldehydes have a -C=O functional group. An aldehyde requires that at least one of the bonds on the C=O group is a hydrogen atom. When the carbonyl group (C=O) has two C atoms bonded to it is classified as a ketone. 5.2 Naming Aldehydes and Ketones
When is a carbonyl group classified as a ketone?
- When the carbonyl group (C=O) has two C atoms bonded to it is classified as a ketone. 5.2 Naming Aldehydes and Ketones Systematic: methanal ethanal propanal butanal Common: formaldehyde acetaldehyde
How are aldehydes and ketones emitted into the atmosphere?
- 4.1 Aldehydes and ketones are emitted into the atmosphere from chemical operations and various combustion sources. In addition, several of these compounds (e.g., formaldehyde and acetaldehyde) are produced by photochemical degradation of other organic compounds.
