The Incomplete Lewis structure below shows all the atoms and sigma bonds for a particular molecule, but nothing else. The molecule has a net charge of 0. Fill in any missing electrons to create the best Lewis structure for the molecule. Make sure to include any non-zero formal charges. D c O: -C x 5 > ?
