Vedclass · Answer

(A) The urea-formaldehyde resin is a thermosetting polymer formed by the condensation polymerization of urea $(NH_2CONH_2)$ and formaldehyde $(HCHO)$.The reaction involves the formation of methylol urea derivatives,which then undergo further condensation to form a cross-linked network structure.The repeating unit of the linear polymer chain formed during the process is represented as $[NH-CO-NH-CH_2]_n$.Therefore,the correct option is $A$.
