22 Νοε 2012 · Aldehydes contain a carbonyl group with at least one hydrogen attached to the carbonyl carbon. They are intermediate in properties between alcohols and alkanes, with higher boiling points than alkanes due to dipole-dipole interactions. Aldehydes are readily oxidized to carboxylic acids and reduced to primary alcohols.
16 Μαΐ 2020 · Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents. If at least one of these substituents is hydrogen, the compound is an aldehyde.
23 Οκτ 2013 · The document provides an overview of aldehydes, including: - Nomenclature of aldehydes using IUPAC and common names. - Physical properties such as boiling points and solubility due to the polar carbonyl group. - Preparation methods including oxidation of primary alcohols and reduction of acid chlorides.
20 Ιουλ 2014 · Aldehydes and Ketones Dr. Talat R. Al-Ramadhany. Introduction Aldehydes are compounds of the general formula RCHO; Ketones are compounds of the general formula RR´CO. The groups R and R´ may be aliphatic or aromatic. Both aldehydes and ketones contain the carbonyl group, C=O, and are often called carbonyl compounds.
The aldehyde and alcohol functional groups can both be parts of the same molecule in an intramolecular reaction 13.4 Reactions Involving Aldehydes and Ketones
21 Ιουλ 2014 · Introduction • Aldehydes and ketones are characterized by the presence of the carbonyl group, perhaps the most important functional group in organic chemistry. • Aldehydes have at least one hydrogen atom attached to the carbonyl carbon atom.
3 Structures of Aldehydes & Ketones. 4 Both aldehydes and ketones contain a carbonyl ( C=O) group. 5 The general formula for the saturated homologous series of aldehydes and ketones is: CnH2nO. 6 In a linear expression, the aldehyde group is often written as: CHO. 7 In the linear expression of a ketone, the carbonyl group is written as: CO.
