Problem: Aspartame is an artificial sweetener marketed under the name Nutra-Sweet. A partial Lewis structure for aspartame is shown below.Aspartame can be classified as an organic compound (a compound based on carbon atoms). The majority of Lewis structures for simple organic compounds have all atoms with a formal charge of zero. Therefore, add lone pairs and multiple bonds to the structure above to give each atom a formal charge of zero when drawing the Lewis structure. Also note that the six-sided ring is shorthand notation for a benzene ring (—C6H5). Benzene is discussed in Section 4‑7. Complete the Lewis structure for aspartame. How many C and N atoms exhibit sp2 hybridization? How many C and O atoms exhibit sp3 hybridization? How many σ and π bonds are in aspartame?

🤓 Based on our data, we think this question is relevant for Professor Sadighi's class at GT.

The Lewis structure of aspartame is:

The hybridization of an atom can be determined by the number of electron groups around it. Electron groups include bond pairs and lone pairs.


4 groups → AX4 notation → 4 hybrid orbitals → sp3 hybridization

3 groups → AX3 notation → 3 hybrid orbitals → sp2 hybridization

2 groups → AX2 notation → 2 hybrid orbitals → sp hybridization
