MCQ
In $C,\,N,\,O$ and $F$ the electronegativity
  • A
    Decreases from carbon to fluorine
  • ✓
    Increases from carbon to fluorine
  • C
    Increases from carbon to oxygen and then decreases
  • D
    Decreases from carbon to oxygen and then increases
✓

Answer

Correct option: B.
Increases from carbon to fluorine
b
Electronegativity increases across a period with increase in atomic number. Hence fluorine is most electronegative and carbon is least electronegative.
