The question asks to identify all the functional groups present in a given molecule. The answer key has "alkene" as one of the functional groups.
Are alkenes and alkynes really counted as functional groups?

Question 1.16 in the Organic Textbook
The answer key says that the compound should be named 2-Isopropyl-1,1-dimethylcyclopentane
Would it also be correct to name the compound 1,1-dimethyl-2-sec-propylcyclopentane?

Re: Quiz 2 Winter 2017
Can somebody explain to me why 10 on the quiz 2 prep is false? This reaction is second order because you are given k=[A]^2. If you look at the equation we derived in class for the half-life of a second order reacion (which is also on the formula sheet), you will find t(1/2) = 1/(k*[A] initial). Thi...

Re: Midterm Winter 2017
For Practice Midterm 2013, question 5b asks to "arrange the following substances in order of increasing standard molar entropy: CHF3, CF4, CH3F, CH2F2" The answer says CH3F<CH2F2<<CHF3<CF4 This seems incorrect, as CF4 should have the least molar entropy and CH2F2 should have the greatest (...

Re: Trouton's rule
Trouton's Rule is the observation that many values of standard entropies of vaporization of liquids are close to 85 J/mol*K. An example of where you can use this is when you are asked to find the approximate standard enthalpy of vaporization of a liquid. Let’s say you want to find the standard entha...

Trouton's Rule [ENDORSED]
According to the book, Trouton's rule is the observation that many enthalpies of vaporization for liquids are close to 85 kJ/mol*K. Self-test 9.7A on page 328 asks to estimate the standard enthalpy of vaporization of liquid bromine, which boils at 59 degrees Celsius, using Trouton's rule. How is thi...

HW Problem 8.93
a) Calculate the work that must be done against the atmosphere for the expansion of the gaseous products in the combustion of 1.00 mol C6H6 (l) at 25 degrees Celsius and 1 bar. In the solutions manual, the products of this combustion are CO2 gas and liquid water. Why is water liquid here and not gas?

Self Test 8.1A on page 264
I have a question about Self Test 8.1A on page 264. I used volume = mass/density to find the volume of water and ice. 100g/1.00 g/cm^-3 = 100cm^-3 = 100mL = 0.001L (water) 100g/0.92g/cm^-3 = 108.7cm^-3 = 108.7mL = 0.001087L (ice) delta V = V(final) - V(initial) = V (ice) - V(water) delta V = 0.00108...
