What are aldehydes?
A compound with a carbon atom which is bonded to a hydrogen atom and double-bonded to an oxygen atom. This is found on the end of the chain, ketones have this carbon in the middle (no H either).
Nomenclature-The name is formed by changing the suffix -e of the parent alkane to -al, so that HCHO is named methanal, and CH3CH2CH2CHO is named butanal.
Examples- to see the names highlight name left of the structure
A primary alcohol reacts with an oxidizing agent to make an aldehyde
R-OH + Ox. Agent→ RH=O
1-Propanol is oxidized to propanal
CH3CH2CH2OH + Ox. Agent—→ CH3CH2CHO
