MCQ
The most polar bond is
  • ✓
    $C-F$
  • B
    $C-O$
  • C
    $C-N$
  • D
    $C-C$
✓

Answer

Correct option: A.
$C-F$
a
Polar character is proportional to electronegativity difference between the atoms. In the given molecules, carbon is common. As fluorine has high electronegativity compared to other atoms, $C - F$ bond is most polar.
