Carboxylic acids

They are miscible with water when short as they are able to make hydrogen bonds they can also do this with acid molecules.

ethanoic acid is vinegar  ( a liquid) and benzoic acid is a solid of white crystalsand will dissolve in hot water

a carboxylic acid will FAIL a 2,4DNP test , the bonds are of the same length 

Acidity 

so how is a molecule which has hydroxyl group an acid 

the negative charge is delocalised and this creates a more stable anionand less likely or it to be reprotonated when the H has been lost to for the H+ that creates the acid traits.The loss of the  hydrogen atom is made easier by the electronegative oxygen pulling on…
