Vedclass · Accepted Answer

$ii, iii$

Vedclass · Answer

(C) $1$. Glyptal is a polyester formed by the condensation of ethylene glycol and phthalic acid. The structure shown in $(i)$ is incorrect as it does not represent the repeating unit of Glyptal.$2$. Bakelite is a cross-linked polymer formed by the condensation of phenol and formaldehyde. The structure shown in $(ii)$ correctly represents the cross-linked structure of Bakelite.$3$. Nylon $6,6$ is a polyamide formed by the condensation of hexamethylenediamine and adipic acid. The structure shown in $(iii)$ correctly represents the repeating unit of Nylon $6,6$: $[-NH-(CH_2)_6-NH-CO-(CH_2)_4-CO-]_n$.$4$. Therefore,both $(ii)$ and $(iii)$ are correct.
