Which would you expect to be more viscous-a
(a) long strands, because they tend to tangle among themselves.
(b) short strands, because of a higher density.
(c) long strands, because of a greater molecular mass.
(d) short strands, because their ends are typically polar.
The correct option for the statement “Which would you expect to be more viscous-a polymer made of long molecular strands or a polymer made of short molecular stands? Why?”
Answer to Problem 10RAT
The correct option for the statement “Which would you expect to be more viscous-a polymer made of long molecular strands or a polymer made of short molecular stands? Why?” is option (a)
Explanation of Solution
The polymer containing longer strands are basically similar to the long nodes in the bowl or long ropes which gets easily tangled around each other. Due to which such kind of polymers can hold more water or solvent molecule on between the existing space as compared to short molecular strands polymers.
Thus,the viscosity of polymer containing longer strands is higher than the polymer containing shorter strands.
Conclusion:
Therefore, the correct option for the statement “Which would you expect to be more viscous-a polymer made of long molecular strands or a polymer made of short molecular stands? Why?” is option (a)
