1. Give the names and structures of two functional groups in organic chemistry that are acidic.2. A mixture contains the following three compounds:OHCOOHAn ether solution of this mixture is extracted with sodium bicarbonate solution to formaqueous layer A and organic layer B. The organic layer B is then extracted with sodiumhydroxide solution to form aqueous layer C and organic layer D. Both solutions A and Care separately treated with hydrochloric acid to give solutions E and F respectively. Givethe structure(s) of the organic solute(s) present in A, B, C, D, E, and F. Explain. Include aflow diagram.3. Write an expression for the acidity constant, Ka, for benzoic acid, C6HCOOH, in terms ofconcentrations.4. Suppose you do not know which layer in your separatory funnel is the aqueous layer, andyou have no information about the density of the solvent, how could you determine whichis the aqueous layer?
