What is the hybridization of each nitrogen atom in aspartame?
There are two nitrogen atoms in aspartame. One is a primary N in R-NH3, while the other is a secondary N in R-NH-R (R represents the rest of the carbon structure). Since both N has three substituents in addition to the already present lone pair, they both have 4 groups attach to them. Thus, they are both sp3 hybridization.
