The ability to quickly recognize the presence or absence of formal charges on atoms is an important skill. You should be able to recognize bonding around the common elements in organic chemistry, and determine the formal charge on the atom based on the number of bonds. The key elements to recognize include carbon, nitrogen, phosphorous, oxygen, sulfur and the halides. For every one of these elements there is a pattern of bonds and lone pairs which will allow rapid determination of formal charge without going through the exercise shown below in determining the formal charge on the nitrogen atom in diethyl amine:…arrow_forward10.
