Elements in the first 2 periods of the Periodic Table do not have access to the d sublevel and must adhere to the octet (or duet H and He) rule. However, the vertical bond dipole has no opposing partner, so the molecule is polar. [1], "IF3" redirects here. 5. F2 reacts with I2 to yield IF3 at −45 °C in CCl3F.
