Polymers

In the following reaction sequence, major products X and Y are acyclic monomers. CH3I [ 3. Red P, Br2\ 4. NH3 (excess)] 1. KCN\ 2. H3O+, X [figure] 500 mol of X completely reacts with 500 mol of Y to give 1 mol of a single biodegradable acyclic copolymer Z as the only product. The amount of Z formed in grams is . Given: Atomic mass (in amu): H : 1, C : 12, N : 14, O : 16, Br : 80

The monomer (X) involved in the synthesis of Nylon 6,6 gives positive carbylamine test. If 10 moles of X are analyzed using Dumas method, the amount (in grams) of nitrogen gas evolved is . Use: Atomic mass of N (in amu) = 14

The molecular weight of U is .
