3. Complete the following flowchart based on this experiment. HA is benzoic acid, B is 4- nitroaniline, and N is naphthalene. organic layer contains organic layer contains evaporate 3.0 M NaOH(aq) organic layer contains evaporate HA + B + N organic solvent organic layer contains 3.0 M HCl(aq) aqueous layer contains |50MHC aqueous layer contains organic layer contains aqueous layer contains evaporate 3.0 M NaOH(aq) aqueous layer contains HA-organic acid B-organic base N-neutral organic compound "Use HB and A where appropriate
When a sample containing different compounds is given, we can separate them on the basis of their solubility. Organic compounds are generally insoluble in water. If an amino group or a carboxylic acid group is present in a compound, we can separate these compounds by reacting with an acid or a base.
When an amine reacts with an acid, a salt is formed. This salt is soluble in an aqueous medium and is insoluble in an organic medium. Using this method we can separate amine from an organic mixture.
When a carboxylic acid reacts with a base, a salt is formed. This salt is soluble in an aqueous medium and is insoluble in an organic medium. Using this method we can separate carboxylic acid from an organic mixture.
Here we have been given a mixture containing benzoic acid (HA), 4-nitroaniline (B), and naphthalene (N). Benzoic acid has a carboxylic acid functional group, 4-nitroaniline (B) has an amine functional group, and naphthalene contains neither acidic nor basic groups.
