Re: Naming [ENDORSED]

In Q6A of the 2013 practice Final Exam, the answer is either 1,5,5,6-tetramethylcyclohex-1-ene or 1,5,5,6- tetramethylcyclo-1-hexene or 1,5,5,6- tetramethylcyclohexene in the solution.... But, I would like to know if 1,5,5,6- tetrameythyl- 1- cyclohexene would also be accepted.

Re: Standard Gibbs Free Energy of Activation

When do we know when the transition state 1 activation energy is greater or less than transition state 2 activation energy? Also, how does it relate to K ? (Referring to the graphing portion of this topic)

Re: Order When Naming

I believe it is supposed to be 3-ethyl-1,1-dimethyl-cyclohexane because 1,1,3 goes before 1,3,3.

Re: Functional Groups [ENDORSED]

When and where will we be required to know the charge of a substituent? Does it have to do with it being a nucleophile or ellectrophile? (why would we need to know the formal charge)

Re: Van't Hoff Equation

Is the Van`t Hoff Equation related to the Arrhenius Equation, or am I totally off the mark? I remember seeing that equation but I thought it was the Arrhenius equation (A variataion or something of it).

Re: Steric Strain

Could someone explain torsional strain and how it applies to the shape of a molecule? How should we refer to it when in a question?

Re: Naming Organic Molecules

How should we include names of halogens when naming the whole molecule (I know the name should include carbon and halogens only)

Re: Naming [ENDORSED]

How do we know in what order we should put the numbers? (because we can start counting from either side of the molecule)

Re: Midterm Winter 2017

Regarding Sig figs, should we keep rounding to the right sig fig throughout the whole question or should we keep using the calculator`s stored values and then just round at the end?

Question about Enthalpy

When looking at the phase change diagram of H2O, is the enthalpy (value of H) value different in the beginning and the end of the second horizontal line? If so, why?
