What do you understand by aldehyde!!
Answers
Hey mate here is your answer
Aldehydes - are an organic compound containing the group —CHO, formed by the oxidation of alcohols. Typical aldehydes include methanal (formaldehyde) and ethanal (acetaldehyde).
Carbonyl groups in aldehydes and ketones may be oxidized to form compounds at the next “oxidation level”, that of carboxylic acids. Addition of water to an aldehyde or ketone gives a product called a hydrate or a gem-diol (two -OH groups on the same carbon). The reaction is both acid-catalyzed and base-catalyzed.

Any compound having the group -CHO. Methyl aldehyde, the simplest aldehyde, is more commonly called formaldehyde, H-CHO, and acetic aldehyde is now more commonly called acetaldehyde. The higher aldehydes may be solids. A reducing sugar typically contains the aldehyde group.
