    CO is practically non-polar since

    A)  The 0-electron drift from C to O is almost nullified by the \[\pi -\]electron drift from O to C

    B)  the\[\sigma -\]electron drift from O to C is almost nullified by the \[\pi -\]electron drift from C to O

    C)  the bond moment is low

    D)  there is a triple bond between C and O

    Correct Answer: A

    Solution :

     \[C\overset{\xleftarrow{\pi }}{\mathop{\xrightarrow[\sigma ]{\pi }}}\,O\] In CO molecule, \[C-O\,\sigma \]moment and \[O-C\] \[\pi -\]moment cancels each other. So that it is non-polar.
