Why does cis-polyisoprene possess elastic property?
Options
- ADue to less branching
- BDue to strong intermolecular forces
- CThe cis-polyisoprene molecule consists of various chains held together by weak van der waals interactions and
- DDue to its crystalline structure
Correct answer
C. The cis-polyisoprene molecule consists of various chains held together by weak van der waals interactions and
Step-by-step solution
Correct Option is : (C) The cis-polyisoprene molecule consists of various chains held together by weak van der waals interactions and has a coiled structure. Thus, it can be stretched like a spring and exhibits elastic properties.
