By looking at the formula one might conclude that CO would have a large dipole moment, wen in fact it has a very small one. Based on the electron arrangement and the formal charge distribution, explain why the dipole moment of CO is so small.
An electron, initially traveling in the +x-direction with a speed of 4 x 105 m/s, enters a uniform electric field directed vertically upward. After traveling in this field for 3.5 x 10-7 s, the electron's velocity is directed 60º above the x-axi
