Naming: Chains vs. rings
When naming organic compounds that have rings in the molecule, do we name based off the longest carbon chain or do we base it off the ring?

Re: Ideal Gas Law
We can find various stuff by using the ideal gas law. For example if we hold Pressure constant, and the moles constant we know that Volume and Temperature are going to be changing. It allows us to picture an ideal condition in which a gas would react.

Re: Units of Reaction Enthalpies
When the question specifies, that it is per mole you would use KJ/mol. Also in addition to that by definition the standard enthalpy of formation is KJ/mol.

Coordination Compounds And Complexes [ENDORSED]
Hi there, so I was reviewing my notes and the textbook but I can't seem to grasp the difference between a coordination compound and complex. I know that a coordination compound is electrically neutral and that it has at least a=one complex present, but then why are coordination compounds and complex...

The octet rule wants the central atom to have 8 electrons (a full octet).

Yes. when forming the bonds you want to try and get the central atom with fc of 0.

Hey there,
I am not quite understanding why the the valence electrons are 4. Could you expand on that explanation please.

Will we need to use the Born-Mayer equation on the quiz? Which equation do we use to calculate lattice energy, I am confused by the given equations from the textbook on pages 73 and 74 regarding calculating potential energy.

Minimum Indeterminacy [ENDORSED]
