What type of chemical bond is this?

Question

Through theorizing and experimentation, scientists have developed a model of a molecule of carbon monoxide (CO). The model has two atomic nuclei vibrating in place, surrounded by electrons in rapid motion. The outermost electrons spend more time near the oxygen nucleus than they spend near the carbon nucleus.

Answer 1

This is a polar covalent bond. The electrons are spending more time near Oxygen because Oxygen is more electronegative when compared to Carbon. It's polar covalent. There is a dipole where one part of the molecule has more of a partial negative charge, near the Oxygen, while the other part of the molecule, near the Carbon is more electropositive.
