The Correct Option is A
Solution and Explanation
Step 1: Identify monomer Y
The given aromatic compound is:
\[
p\text{-methyl acetophenone}
\]
On oxidation with:
\[
KMnO_4/OH^-
\]
followed by
\[
H_3O^+
\]
both side chains are converted into carboxylic acid groups.
Thus Y is:
\[
HOOC-C_6H_4-COOH
\]
which is:
Terephthalic acid
Step 2: Identify monomer Z Ethene reacts with cold dilute alkaline \(KMnO_4\) to form: \[ HO-CH_2-CH_2-OH \] which is: Ethylene glycol
Step 3: Identify polymer X Terephthalic acid + Ethylene glycol undergo condensation polymerisation to form: \[ [-O-CH_2-CH_2-OCO-C_6H_4-CO-]_n \] This polymer is: Terylene \[ \boxed{\text{Polymer X = Terylene}} \] Therefore, the correct answer is: \[ \boxed{(A)} \]
Step 2: Identify monomer Z Ethene reacts with cold dilute alkaline \(KMnO_4\) to form: \[ HO-CH_2-CH_2-OH \] which is: Ethylene glycol
Step 3: Identify polymer X Terephthalic acid + Ethylene glycol undergo condensation polymerisation to form: \[ [-O-CH_2-CH_2-OCO-C_6H_4-CO-]_n \] This polymer is: Terylene \[ \boxed{\text{Polymer X = Terylene}} \] Therefore, the correct answer is: \[ \boxed{(A)} \]
