DRAW IT Ø Suggose you had an organic molecule such as cysteine (see Figure 4.9, sulfhydryl group example), and you chemically removed the —NH2 group and replaced it with —COOH. Draw this structure. How would this change the chemical properties of the molecule? Is the central carbon asymmetric before the change? After?

DRAW IT Suppose you had an organic molecule suchas cysteine (see Figure 4.9, sulfhydryl group example),and you chemically removed the —NH2 group andreplaced it with —COOH. Draw this structure. Howwould this change the chemical properties of themolecule? Is the central carbon asymmetric beforethe change? After?
In an ammonia molecule, one nitrogen atom (atomic number = 7; 1s² 2s²2p³)
forms covalent bonds with three hydrogen atoms. Draw a diagram of an ammonia
molecule. Show all valence electrons, lone pairs, molecular geometry, and partial
charges (assume sp³ hybridization).
