Which of the following statements regarding carbon monoxide is incorrect?

Which of the following statements regarding carbon monoxide is incorrect?
  1. A triple bond exists between $\mathrm{C}$ and $\mathrm{O}$
  2. $\mathrm{O}$ atom carries negative charge and $\mathrm{C}$ carries positive charge
  3. Dipole moment of $\mathrm{CO}$ is low as compared to its calculated value from the charge separate and bond distance
  4. Bond order of $\mathrm{CO}$ is 3.

Solution

The CO molecule is represented as : $\overline{\mathrm{C}} \leftrightarrows \stackrel{+}{\mathrm{O}}$ :
Dipole moment is low due to pull of bonding electrons towards more electronegative oxygen atom.
