After Stoichiometric/Equivalence Pt

I think I under stand that at the Stoichiometric point the concentrations of titrant added either strong acid/base is equal to the concentration of the weak acid/base, but what happens to the solution once it is past it's stoichiometric point?

Heteronuclear Molecule MO notation

In the example given to us in class where oxygen has a higher electronegativity value compared to carbon, the oxygen orbitals are placed lower than the carbon orbitals. Would we continue to do this for all heteronuclear molecules or just molecules with a significantly large differences in electroneg...

cis/trans naming

Are we ever going to encounter an example where the elements are given and we have to determine whether the compound is a cis or trans compound?

Re: Chap 4 Q 75 b

In regards to the spin pairing you wrote down this is correct as the sp3 hybridization is the right model for Oxygen due to the four regions of electron density. The two unpaired spins represents the electrons available for bonding (2) and the paired electrons in the p3 orbital represent the amount ...

Re: Chapter 3#59

With ClO, there is an odd number of electrons so Cl is going to have a radical on it. Is it enough to say that the Cl is going to have the unpaired electron solely on the basis that Cl has an odd number of valence electrons? I am wondering if the electronegativities come into play with this problem...

Units for electronegativity

If electronegativity is a function of ionization energy and electron affinity, how is it that there are no units associated with these values?

Re: Increasing polarization

N^3- would have a larger ionic radii because it's electrons experience less of a pull, so they have more polarizability. To expand on what the above quote is saying, the lessened pull is a result of lessened electrostatic coulombic force by the N^3- due to the above mentioned lessened effective nuc...

ion vs lone pair coordinate covalent bonding

I know that coordinate covalent bonds occur with Group 13 atoms such as boron with F- in BF4, but is it still called a coordinate covalent bond when two molecules interact and one molecule accepts the lone pair of the other to complete the octet such as, BF3 (g) + :NH3 (g) = NH3BF3 ?
