Define formal charge and explain how to calculate it. What is the purpose of the formal charge? Organic compounds are composed mostly of carbon and hydrogen but also may have oxygen, nitrogen, and/or halogens in the formula. Formal charge arguments work very well for organic compounds when drawing the best Lewis structure. How do C, H, N, O, and Cl satisfy the octet rule in organic compounds so as to have a formula charge of zero?
Formamide, HC(O)NH2, is prepared at high pressures from carbon monoxide and ammonia, and serves as an industrial solvent (the parentheses around the O indicate that it is bonded only to the carbon atom and that the carbon atom is also bonded to the H and the N atoms). Two resonance forms (one with formal charges) can be written for formamide. Write both resonance structures, and predict the bond angles about the carbon and nitrogen atoms for each resonance form. Are they the same? Describe how the experimental determination of the HNH bond angle could be used to indicate which resonance form is more important.
Based on the atom connectivity shown bellow,evaluate the four resonance structure for the thiosulfate ion S2O3 ^2-. Use curved arrows to indicate how you get from one resonance structure to another. Assign formal changes to all atoms and determine which of these resonance structure is the most stable based on a formal charge analysis Explain your answer thoroughly. Look at the picture.

Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. (Be sure your answers are consistent with the formal charges on the formulas.) The number of unshared pairs at atom a is со b The number of unshared pairs at atom b is H3C CH3 The number of unshared pairs at atom c is The number of unshared pairs at atom a is b H3C- The number of unshared pairs at atom b is CCH2 The number of unshared pairs at atom c is
1.) What is the Lewis structure for the methylthiolate anion, CH3S-. Carbon is the central atom. Show any nonzero formal charges. 2.) Proteins are large molecules that affect almost every function of the human body. Proteins are composed of smaller building blocks called amino acids. The simplest amino acid is glycine. When dissolved in water, two atoms in a glycine molecule have a formal charge. In the lewis structure of glycine C2H5NO2 all bonds are drawn (image is provided), but the unbonded valence electrons (lone pairs) are missing. Copy the structure and draw the missing valence electrons (lone pairs). Locate the 2 atoms that have a nonzero formal charge. Calculate the charge at these sites.
