Verified by Experts

Monomers present in `"["-overset(O)overset(||)C-(-CH_2)_8-overset(O)overset(||)C-NH-(CH_2)_6-NH"]"` are decane dioic acid `HOOC-CH_(2)-)_(8)COOH` and hexamethylene diamine `H_(2)N-(CH_(2)-)_(6)NH_(2)`
ii)Monomers present in `(-NH-CO-NH-CH_(2)-)_(n)`are urea`CO (NH_(2))_(2),`formaldehyde`HCHO`.
