The dipole moment of a molecule is a measure of its polarity, which is determined by the difference in electronegativity between the atoms and the distance between them. For carbon monoxide CO , the electronegativity values are 2.55 for carbon C and 3.44 for oxygen O .To calculate the dipole moment , we can use the formula: = Q dwhere Q is the charge difference between the atoms in Debye, D and d is the distance between the atoms in ngström, .First, we need to find the charge difference Q between the carbon and oxygen atoms. The difference in electronegativity between C and O is:EN = 3.44 - 2.55 = 0.89Since the bond in CO is a triple bond, we can assume that the charge difference is approximately equal to the difference in electronegativity:Q EN = 0.89 DNext, we need to find the distance between the carbon and oxygen atoms d . The bond length of CO is approximately 1.128 .Now, we can calculate the dipole moment : = Q d = 0.89 D 1.128 1.00 DTherefore, the dipole moment of carbon monoxide CO is approximately 1.00 Debye.
