Among cellulose, polyvinyl chloride, nylon and natural rubber, the polymer in which the intermolecular force of attraction is weakest in
  1. nylon
  2. polyvinyl chloride
  3. cellulose
  4. natural rubber

Solution

$ \text { Nylon has amid linkage capable of forming intermolecular } \mathrm{H} \text {-bonding as } $
Due to $\mathrm{H}$-bonding, nylon has strong intermolecular attraction. Cellulose is a polyhydroxy compound, also capable of forming strong intermolecular $\mathrm{H}$-bonding. Polyvinyl chloride is a polar polymer due to carbon chlorine bond and it possess strong dipole-dipole attraction. Natural rubber is poly (isoprene), a hydrocarbon, possess weak van der Waal's attraction.
