Which of the following have Lewis structures that $d o$ not obey the octet rule: $\mathrm{NF}_{3}, \mathrm{~B}(\mathrm{OH})_{3}, \mathrm{SiF}_{6}^{2-}, \mathrm{SO}_{3}$ $\mathrm{PH}_{4}^{+}, \mathrm{PO}_{4}^{3-}, \mathrm{ClO}_{2}, \mathrm{C}_{2} \mathrm{H}_{4}, \mathrm{SO}\left(\mathrm{CH}_{3}\right)$
Draw the dominant Lewis structures for these chlorineoxygen molecules/ions: $\mathrm{ClO}, \mathrm{ClO}^{-}, \mathrm{ClO}_{2}^{-}, \mathrm{ClO}_{3}^{-}, \mathrm{ClO}_{4}^{-}$. Which of these do not obey the octet rule?
