The residue obtained was diluted with 20% NaOH and the aq layer was extracted with EtOAc . of uses of Base * Improve solubility of acidic Learn organic chemistry 1 reagents with free interactive flashcards. Base sensitive substrates may not NaOH The basic hydrolysis of a nitrile to a carboxylic acid is typically done with a hydroxide base (ex. The org layer was dried ( Na2SO4 ) and concentrated to … Generally this can be as a base or as a nucleophile. The reaction with sodium is a redox reaction (note the changing oxidation state of hydrogen from +1 to 0), whereas that with NaOH is merely acid-base. $\endgroup$ – orthocresol ♦ Sep 17 '16 at 6:51 The combined org extracts were washed with H2O (2 x 20 mL), brine, dried ( Na2SO4 ), and … reflux). NaOH or KOH) in an appropriate solvent (ex.

After completion of the reaction, ice-cold H2O was added to the reaction mixture.
