If they give bromine water test, what do they form?


I think that aldehydes will get oxidised and so decolourise bromine water but I don't know if that happens in normal conditions.




The answer is yes. Aldehydes will decolourise bromine water.


The oxidation of aldehydes to acids is discussed in this answer [Does Br2/H2O oxidize all aldehydes?](https://chemistry.stackexchange.com/questions/70893/does-br2-h2o-oxidize-all-aldehydes?rq=1)


In addition alpha-bromination of the aldehyde *via* the acid catalysed bromination of the enol is a well-documented process. <https://chem.libretexts.org/LibreTexts/Athabasca_University/Chemistry_360%3A_Organic_Chemistry_II/Chapter_22%3A_Carbonyl_Alpha-Substitution_Reactions/22.03_Alpha_Halogenation_of_Aldehydes_and_Ketones>
