Solution

The linear form of carbon dioxide has zero dipole moment, even though it has two polar bonds. In CO2, the dipole moments of two polar bonds (CO) are equal in magnitude but have opposite direction. Hence, the net dipole moment of the CO2 is,

μ = μ1 + μ2 = μ1 + (-μ1) = 0

In this case μ = `vec mu_1 + vec mu_2`

`= vec mu_1 + vec ((-mu_1) = 0`
