A) It is a linear, unbranched polymer of tetrafluoro ethylene
B) It has very high thermal stability
C) Polymer molecules are associated by strong dipole-dipole attraction
D) All of the above
Correct Answer: D
Solution :
Due to symmetry of\[{{F}_{2}}C=C{{F}_{2}}\]and strength of \[C-F\]bond, branching does not take place and a linear chain teflon is always formed. High bond energy of\[C-F\]bond gives high thermal stability to polymer. Large electronegativity difference of C and F makes\[C-F\]bond highly polar.
