The more stable carbocation in the given pair is to be identified. Concept introduction: The carbocation becomes stable when atoms or groups attached to it stabilize the positive charge on it. The induced polarization of sigma bond is called inductive effect. The electron donating atom or group has a positive inductive effect that stabilizes the positive charge on carbon. The electron withdrawing atom or group has negative inductive effect that destabilizes the positive charge on carbon. The alkyl groups have electron donating inductive effect and stabilize carbocation (carbon with positive charge). The alkyl groups also show delocalization of electrons in sigma bonds through hyperconjugation and stabilized carbocation. Hyperconjugation is the delocalization of electrons in C-H sigma bond of methyl/alkyl group.

Acetic acid is added to DI water at an initial concentration of 10 -6 M (Ka=1.8x10-5) A. Using the "ICE" Method, what would the pH be at equilibrium? State assumptions and show your work. B. Using the simultaneous equations method, what would the pH be at equilibrium? Show your work

1. Show that the change in entropy for a fixed amount of ideal gas held at a constant temperature undergoing a volume change is given by the simple equation AS = NkB In Hint: Start with the equation M dS = du + (Œ) dv - Ž (#) an, dU du+av-dN; j=1 Why doesn't the equation for the entropy of an ideal gas depend on the strength of the intermolecular forces for the gas?

2. Make an ice cube at 1 bar pressure by freezing an amount of liquid water that is 2 cm x 2 cm x 2 cm in volume. The density of liquid water at 0 °C is 1.000 g cm³ and the density of ice at 0 °C is 0.915 g cm³. Note that this difference in density is the reason your water pipes burst if they freeze and why you shouldn't forget to take your bottle of pop out of the freezer if you put it in there to try and cool it down faster. A. What is the work of expansion upon freezing? B. Is work done on the system or by the system?
