Formal Charge Exercise - Michigan State University
Formal Charges. Questions 1 through 8 refer to the group of structures shown on the left. Enter appropriate letters from A through K in each answer box. If no structure fits the property enter the letter X. Do not enter superfluous characters, since they will be counted as incorrect answers..
Resonance Exercise - Michigan State University
The first part of this question requires you to locate formal charges and electron deficient atoms (atoms that have not achieved a valence shell electron octet through covalent sharing). Enter appropriate letters (from A to L) in each answer box. If no structure fits the property enter the letter X. Do not enter superfluous characters, since ...

2. Molecular Orbitals. Just as the valence electrons of atoms occupy atomic orbitals (AO), the shared electron pairs of covalently bonded atoms may be thought of as occupying molecular orbitals (MO). It is convenient to approximate molecular orbitals by combining or mixing two or more atomic orbitals.
•This eliminates the charge on the phosphorus and the charge on one of the oxygens. •The lesson is: When the central atom is on the 3rd row or below and expanding its octet eliminates some formal charges, you cando so. •But,you don’t have to.
Molecular Structure & Bonding - Michigan State University
Consider a hydrocarbon with a molecular structure consisting of a simple chain of four carbon atoms, CH 3 CH 2 CH 2 CH 3. The molecular formula is C 4 H 10 (the maximum number of bonded hydrogens by the 2n + 2 rule). If the four carbon atoms form …

Elements and. Comic Books. Four elements, hydrogen, carbon, oxygen and nitrogen, are the major components of most organic compounds. Consequently, our understanding of organic chemistry must have, as a foundation, an appreciation of the electronic structure and properties of these elements. The truncated periodic table shown above provides the ...

Acids & Bases - Michigan State University
As shown at the top of the following drawing, coordinate covalent bonding of a phosphorous Lewis base to a boron Lewis acid creates a complex in which the formal charge of boron is negative and that of phosphorous is positive. In this complex, boron acquires a neon valence shell configuration and phosphorous an argon configuration.

Try drawing Lewis-structures for the sulfur atoms in these compounds. If you restrict your formulas to valence shell electron octets, most of the higher oxidation states will have formal charge separation, as in equation 2 above. The formulas written here neutralize this charge separation by double bonding that expands the valence octet of sulfur.
