how to differentiate between aldehyde and alchol
dikshitkumar119:
Tertiary alcohols don't react with oxidizing agents because they do not have a hydrogen on the carbon atom to which the OH group is attached. Aldehydes can be further oxidized to carboxylic acids. Reduction is the reverse of the oxidation reaction. ... This produces an alcohol.

An alcohol contains OH group and an aldehyde contains HC=O group.
Alcohols under go esterification reaction but aldehydes do not.
Aldehydes reduces tollen’s reagent but alcohols do not.
Aldehydes react with 2,4-Dinitrophenylhydrazine to form yellow, orange or reddish orange precipitate (hydrazone formed) while alcohols do not react.
Alcohols react with ceric nitrate converts ceric ion to electronic structure producing colour change from yellow to red where aldehydes do not react
Aldehydes exclusively react with Schiff’s reagent giving magenta coloured conjugated product where alcohols do not react.

An alcohol group consists of a hydroxyl group attached to the carbon chain (R-OH)An aldehyde group is a carbonyl group attached to a terminal carbon in the chain (R-CH=O) . And yes, it HAS to be a terminal carbon. If the carbonylgroup is connected to a carbon atom within the chain, then you’ll have a ketone.
