Vedclass · Answer

(A) Nylon-$6,6$ is synthesized by the polycondensation of hexamethylenediamine and adipic acid.$n HOOC-(CH_2)_4-COOH + n H_2N-(CH_2)_6-NH_2 \rightarrow [CO-(CH_2)_4-CO-NH-(CH_2)_6-NH]_n + 2n H_2O$In hexamethylenediamine $(H_2N-(CH_2)_6-NH_2)$,the number of $-CH_2-$ groups is $6$.In adipic acid $(HOOC-(CH_2)_4-COOH)$,the number of $-CH_2-$ groups is $4$.Therefore,the number of $-CH_2-$ groups in $X$ and $Y$ are $6$ and $4$ respectively.

Nylon-$6,6$ is a condensation polymer of two monomers $X$ and $Y$. The number of $-CH_2-$ groups in $X$ and $Y$ are respectively
