Disregard any structure with formal charges other than 0 ...Since oxygen is more electronegative then nitrogen, the negative charge is more stable when its on the oxygen atom. Therefore, structure #1 is more stable (preferred) than structure #2. Structures #3-#5 are even less stable. They either violate the octet rule (#4, #5) and / or have charges (sometimes multiple) on more than one atom (#3-#5). Share.
