Question

In which molecule are the bonds most polar?

A) F2

B) NF3

C) OF2

D) CF4

Answer 1

Answer #1

F2 is non polar because both molecules are same.

The electronegativity order of atom is:

C < N < O < F

So, the electronegativity difference would be maximum in C-F and least in O-F

So, polarity of bond is:

O-F < N-F < C-F

So,

C-F bond in CF4 is most polar.

Answer: D
