Question

general organic chemistry liquid-liquid extraction

This experiment does involve chemical reactions that involve amine of your unknown. Choose one of those acids and one of the to include those reactions in the appropriate section of the PreLab Write out chemical equations for the reaction of: an amine (RNH_2) with hydrochloric acid a carboxylic acid (RCOOH) with sodium bicarbonate a phenol (ArOH) with sodium hydroxide Prepare a flow chart similar to the one shown in Figure 6-1 the of one acid, one base, and one neutral compound from the will not be separating out a phenol, so omit that from the flow chart circle and label the functional groups in the molecule.

Answer 1

2.a. Reaction of amine with hydrochloric acid.

$R-NH_2 (aq) + HCl(aq) \rightarrow R-NH_3^+Cl^-(s)$

b. Reaction of carboxylic acid with sodium bicarbonate

$R-COOH (aq) + NaHCO_3(aq) \rightarrow R-COONa(aq)+H_2O(l)+ CO_2(g) \uparrow$

c. Reaction of aromatic phenol with sodium hydroxide

$ArOH (s) + NaOH(aq) \rightarrow ArONa(aq)+H_2O(l)$
