aldehyde
Alcohols may be oxidized to give aldehydes, ketones, and carboxylic acids. The oxidation of organic compounds generally increases the number of bonds from carbon to oxygen, and it may decrease the number of bonds to hydrogen.
The term aldehyde is derived from the New Latin alcohol dehydrogenatum, which translates to "dehydrogenated alcohol".1
This name reflects the chemical relationship between the two classes of compounds: aldehydes are, in principle, produced from alcohols through the process of dehydrogenation, which involves the removal of hydrogen atoms.2
