Ketones and Aldehydes

Ketones and Aldehydes. Aldehyde: An organic molecule with an oxygen double bonded to one of the two outer carbons on the chain. Aldehyde? What?. → → Pentane Pentane → Pentan Pentan → Pentanal Pentanal = . Aldehyde Nomenclature. Ignore the oxygen and name

aldehydes and ketones

Aldehydes: Structure and Nomenclature. General formula: RCHO or RCH=OThe aldehyde group is always at the end of a chainIUPAC system: Select the longest continuous carbon chain that contains the C=O group and replace the ending by the suffix al.The CHO group is assigned the number 1 position and takes precedence over other functional groups that may the present such as

Aldehydes and ketones

Aldehydes and ketones. Chapter 15. The carbonyl group. Aldehydes and ketones are among the first examples of compounds that possess a C-O double bond that we’ve seen (oxidation of alcohols section, Ch-14).

Ketones and Aldehydes

Ketones and Aldehydes. =>. 4.1 Carbonyl Structure. Carbon is sp 2 hybridized. C=O bond is shorter, stronger, and more polar than C=C bond in alkenes. 4.2 Carbonyl Compounds. =>. 4.3 Naming Aldehydes. IUPAC: Replace - e with - al . The aldehyde carbon is number 1.

Aldehydes and Ketones

- Both aldehydes and ketones contain carbonyl group C=O. - The difference between aldehyde and ketone was found to be:. Aldehydes and Ketones. In aldehyde C=O attach with H and R i.e. In ketone C=O attach with two R. General formulae of aldehyde and ketones.
