Practice every matching question in batches of 20, with every available option.
Monomer A of a polymer on ozonolysis yields two moles of HCHO and one mole of CH\(_3\)COCHO.
(A) Deduce the structure of A.
(B) Write the structure of "all \(cis\)" forms of polymer of compound A.
Match the chemical substances in Column I with type of polymers/type of bonds in Column II. Indicate your answer by darkening the appropriate bubbles of the 4 \(\times\) 4 matrix given in the ORS.
| Column I | Column II | ||
|---|---|---|---|
| (A) | cellulose | (P) | natural polymer |
| (B) | nylon-6, 6 | (Q) | synthetic polymer |
| (C) | protein | (R) | amide linkage |

In the following reaction sequence, major products $\mathbf{X}$ and $\mathbf{Y}$ are acyclic monomers.
500 mol of $\mathbf{X}$ completely reacts with 500 mol of $\mathbf{Y}$ to give 1 mol of a single biodegradable acyclic copolymer $\mathbf{Z}$ as the only product. The amount of $\mathbf{Z}$ formed in grams is $\_\_\_\_$ .
Given :
Atomic mass (in amu): $\mathrm{H}: 1, \mathrm{C}: 12, \mathrm{~N}: 14, \mathrm{O}: 16, \mathrm{Br}: 80$
