Options
- Aa → I V , b → ( I I ) , ( c ) → ( I ) , ( d ) → ( I I I )
- B( a ) → I I I , ( b ) → ( I ) , ( c ) → ( I V ) , ( d ) → ( I I )
- C( a ) → I I I , ( b ) → ( I ) , ( c ) → ( I I ) , ( d ) → ( I V )
- D( a ) → I I , b → I V , c → I , d → I I I
Correct answer
B. ( a ) → I I I , ( b ) → ( I ) , ( c ) → ( I V ) , ( d ) → ( I I )
Step-by-step solution
Ziegler-Natta is used in the production of high-density polymer. The addition polymerisation of Acrylonitrite in presence of a peroxide catalyst leads to the formation of Polyacrylonitrile Nylon - 6 is a condensation polymer made from caprolactum Novolac is the linear product of phenol-formaldehyde which is produced by condensation reactions in the presence of either acid or base.
