Unformatted text preview: n average of these structures, so each C‐O bond is equal in length. +2 average between single and double bond Each C‐O has a bond order and a bond length between a single and a double bond. 3 4. Draw the single best Lewis structure, obeying the octet rule whenever possible, for each of the following compounds. Be sure to list any non‐zero formal charges on each atom, and identify the overall charge of ions using brackets. +3 for correct connectivity, lone pairs, and bonds; if correct, +1 correct formal charges and bracket (a) IFCl2 (b) Selenium dioxide (c) CCl4 (d) PCl2ˉ O
