Question

Q: A segment of polyethylene is shown. Which statemento) below are true about this polymer? Choose all that apply The polymer contains polar bonds. Overall, the polymer is non-polar because symmetry cancels bond polarity. The polymer has non-polar bonds. Overall, the polymer is polar because of an absence of dipole symmetry of the polar bonds. Q: A segment of PTFE is shown. Which statement(s) below are true about this polymer? Choose all that apply The polymer has very polar bonds. Overall, the polymer is non-polar because symmetry cancels bond polarity The polymer has non-polar bonds. Overal, the polymer is polar because of an absence of dipole symmetry of the polar bonds.

Explanation / Answer

First question : answer

The polymer has non polar bonds

Explanation: electron pair between C and H are equally shared

Second question: answer is

Overall the polymer is non polar because the symmetry cancels bond polarity

Explanation: the electron pair between C and F will be near to fluorine but in equal and opposite direction therefore no net dipole moment as a result polymer is non polar.
