Which are the monomeric repeating units of Nylon-6 and Nylon-6,6 ?

Explanation

The monomeric repeating unit of nylon-6 is `-NH-(CH_(2))_(5)-overset(overset(O)("||"))(C)-` which is derived from caprolactam
The monomeric repeating unit of nylon 6,6 is derived from two monomer hexamethylenediamine and adipic acid and has the following structure :
`-NH-(CH_(2))_(6)-NH-overset(overset(O)("||"))(C)-(CH_(2))_(4)-overset(overset(O)("||"))(C)-`
