This web page very clearly outlines the process of dealing with complex substituents (or, substituents within substituents). It also has a useful table of tert, neo, sec, etc.

Re: Work of expansion question?
Also, you use the equation w=-P_{ext}\Delta V for when external pressure is constant. The work depends on a change in volume. As the system expands, energy is lost, so work is negative. In general, work done on a system is positive (increases energy of the system), and work done by a system is negat...

Re: Entropy
Well, the "glossary definition" of residual entropy is:
The nonzero entropy t T=0 in certain systems, which is due to a surviving disorder in the orientation of molecules.

Work (w)
What is the difference between work done on a system vs. work done by a system?

Pressure-Volume work
What is the significance of the relationship between pressure and volume in the pressure-volume curve? (Where the space underneath the curve represents work.)

Re: which model of M.O?
For a heteronuclear molecule such as CO, always use the MO diagram for the atom in the molecule with the lowest atomic number. Since for C: Z=6, and for O: Z=8, use the MO arrangement for Z<8.

Re: HW #3.57b
This is from the solutions manual: "Because H is electropositive, its placement near an oxygen atom makes it less likely for that oxygen atom to donate a lone pair to an adjacent atom." Also, the arrangement of three oxygens attached to one sulfur, (with the hydrogen on one of the oxygens)...

Re: Homework Problem 3.51
The Lewis structure for HClO has O in the middle because this arrangement allows for oxygen and chlorine to each have a formal charge of 0. If Cl were placed in the middle instead, Cl would have a formal charge of +1, and O would have a formal charge of -1. Formal charges of value 0 are favorable si...
