• B. $\left(A\right)\to \left(i\right),\left(B\right)\to \left(ii\right),\left(C\right)\to \left(iv\right),\left(D\right)\to \left(iii\right)$
• C. $\left(A\right)\to \left(iii\right),\left(B\right)\to \left(iv\right),\left(C\right)\to \left(i\right),\left(D\right)\to \left(ii\right)$
• D. $\left(A\right)\to \left(iv\right),\left(B\right)\to \left(iii\right),\left(C\right)\to \left(ii\right),\left(D\right)\to \left(i\right)$

Answer 1

Answer: (D)

Buna-N is a polymer of acrylonitrile $(C{H}_2=$ $CH(CN)$ )and butadiene $\left(C{H}_2=CH-CH=C{H}_2\right)$ Nylon-66 is a polymer of hexamethylenediamine $\left(N{H}_2-{\left(C{H}_2\right)}_6-N{H}_2\right)$ and adipic acid (HOOC${\left(C{H}_2\right)}_4-COOH)$.
Dacron (terylene) is a polymer of terephthalic acid.

Glycol $\left(HOC{H}_2-C{H}_{2}OH\right)$
Glyptal plastic is a polymer of phthalic acid
