MCQ
The bond having the highest bond energy is
  • A
    $C = C$
  • B
    $C = S$
  • C
    $C = O$
  • D
    $P = N$

Answer

$(c)$ More effective axial and sideways overlapping between atomic orbitals of  carbon and those of oxygen atom is higher due to smaller size of oxygen atom. Oxygen is more electronegative than oxygen atom. due to these factors $CO$ has highest bond energy.
