Question

The polymer formed by \(X\) and \(Y\) is

• A. Glyptal
• B. Bakelite
• C. Nylon 6,6
• D. Dacron

Hint:

Remember the important polymer formations: \[ \boxed{ \text{Phenol + Formaldehyde} \longrightarrow \text{Bakelite} } \] \[ \boxed{ \text{Ethylene glycol + Terephthalic acid} \longrightarrow \text{Dacron} } \] \[ \boxed{ \text{Glycerol + Phthalic acid} \longrightarrow \text{Glyptal} } \]

Answer 1

The Correct Option is B

Step 1: Identify \(X\). Controlled oxidation of methane in presence of \[ \mathrm{Mo_2O_3} \] produces \[ \boxed{\mathrm{HCHO}} \] (formaldehyde).

Step 2: Identify \(Y\). Chlorobenzene on treatment with \[ \mathrm{NaOH} \] at high temperature and pressure followed by acidification gives \[ \boxed{\mathrm{C_6H_5OH}} \] (phenol).

Step 3: Identify the polymer. Phenol reacts with formaldehyde to produce \[ \boxed{\text{Bakelite}.} \] Hence, \[ \boxed{(B)} \] is the correct answer.
