On complete hydrogenation, natural rubber produces
Options
- Aethylene-propylene copolymer
- Bvulcanised rubber
- Cpolypropylene
- Dpolybutylene
Correct answer
A. ethylene-propylene copolymer
Step-by-step solution
n C H 2 = C - C H | C H 3 = C H 2 → ( - C H 2 - C = C H | - C H 3 C H 2 - ) n N a t u r a l rubber → H 2 / P t - C H 2 - C H - | C H 3 C H 2 - C H 2 - n
