i was asked to draw the Lewis structure of NO2-, and to write the formal charge of any atoms. so in the picture you can see my tried (the red number is...
Enter the formula of a chemical compound to find the oxidation number of each element. A net ionic charge can be specified at the end of the compound between { and }. For example: ZnCl4{2-} or NH2NH3{+}. Enter just an element symbol to show the common and uncommon oxidation states ...

Additionally, an empty 2p orbital of B in the ring plane allows the formation of a donor–acceptor interaction with electron-rich atoms (Lewis basic sites) of the ortho substituent. Nitro substitution in the 2-position is associated with a small positive energetic effect (1.12 kcal/mol), in ...
