Re: SN2 vs "Nucleophilic sub"

Nucleophilic substitution is replacing a nucleophile with another nucleophile I'm assuming?

Chair conformation

For the cyclohexane to flip conformations from one chair to the other, it has to go through the boat conformation correct? Therefore it has to go through the higher energy state to get to the lower?

Common vs IUPAC naming

I know he said we don't need to know the common naming but in the class examples he combined both common and IUPAC. Should we know both for the quiz?

Equilibrium Redox Equations and Calculating their standard cell potentials

I am having trouble understanding how to balance the equilibrium redox equations, especially in problem 14.15. How do I determine the half reactions for oxidation and reduction?

Entropy of molecules with same number of atoms but different bonds

Say two molecules have the same number of atoms and similar complexity, but one is bonded by double bonds while the other is only bonded by single bonds? How is entropy affect by these bonds?

First Law of Thermodynamics Practice Problem [ENDORSED]

A system was heated by using 300. J of heat, yet it was found that its internal energy decreased by 150. J (so \Delta U=-150. J). Calculate w. To calculate work, we would move the equation around to be w=\Delta U-q right? And then we would have w = -150. J - 300. J = -450. J. Since the energy from w...
