Which one of the following is NOT a haloalkane?
I have went through each option:
A) Freon is $\ce{CCl2F2},$ which is derived from methane
B) Teflon is a polymer of $\ce{-F2C-CF2 -}$ (or) $\ce{(C2F4)_n},$ derivative of 1,2-difloroethene. Here, carbon is saturated, which means no double or triple bond is present.
C) Iodoform is $\ce{CHI3},$ which again is a derivative of methane.
D) Vinyl chloride is unsaturated thus it does not classify as an haloalkane.
