Question

Which of the following is a polar molecule?

Answer 1

Answer:

B. A carbon monoxide molecule(CO)

Explanation:

CO is polar because oxygen is more electronegative than carbon, so it gives oxygen a partial negative charge and carbon and partial positive charge. This causes a net dipole moment. CO2 is linear with no net dipole moment because each C-O bond is equal and opposite to each other, so they equal 0, which makes them non polar.

Answer 2

The answer will be (B) hope this helps!
