Re: Ether naming

When naming, treat ethers like substituents. That is why the -oxy- appears before the main carbon chain.They do not effect the name of the longest parent chain.

Re: Stability

You need to look at the values of ∆G_rxn to determine whether the reactants(∆G_rxn>0) or products(∆G_rxn<0) are more thermodynamically stable. To determine kinetically stability, we need to look at how large or small ΔG‡ is. If ΔG‡ is small, it is kinetically unstable. If ΔG‡ is large, it is more ki...

Re: Substituent -yl ending

I believe that this is correct. Only in hydrocarbons do we use the ending -yl.

Re: Midterm 2014 Question 8

I agree with Ilana because in the problem we are given the standard cell potential, which is always at 25C

14.13b HW Question

Question:Write the half-reactions and the balanced equation for the cell reaction, and the cell diagram for the galvanic cell: b)Ce^4+(aq)+ I-(aq) -> I2(s) + Ce^3+ (aq) I understand how to get the half reaction and the balanced equation, but the answer for the cell diagram reads: Pt(s) |I- (aq) | I2...

Cell Diagram question

I missed the reasoning behind why platinum or graphite is needed in a cell diagram, can someone explain this please?

Difference in equation for volume and pressure

How does the equation for internal energy change when it is at a constant volume vs. when it is at a constant pressure?

Re: Entropy and Enthalpy

From what I understand, entropy is the amount of disorder in a system, while enthalpy is the amount of heat released/absorbed at a constant pressure (from the course reader). I'm not sure if just these plain explanations help, but they are two different thermodynamic properties. Also, enthalpy has u...
