Vedclass · Answer

(A) Dextron (also known as Dexon) is a biodegradable polymer formed by the copolymerization of lactic acid $(CH_3CH(OH)COOH)$ and glycolic acid $(HOCH_2COOH)$.This reaction involves the elimination of water molecules to form an ester linkage,resulting in a polyester copolymer.The chemical reaction is:$n \ CH_3-CH(OH)-COOH + n \ HO-CH_2-COOH \rightarrow -[O-CH(CH_3)-CO-O-CH_2-CO]_n- + 2n \ H_2O$Thus,the correct monomers are lactic acid and glycolic acid.
