It is a good nucleophile due to its size. See image

You likely won't be asked to draw all of the isomers, especially for very long chains... you will be asked to draw 3 or so. However, if is asked to "draw all isomers," follow these steps: THE FIVE STEPS FOR DRAWING ISOMERS: 1) Draw the main chain. 2) Draw the main chain minus 1 carbon, and...

if you mean the double dagger, it signifies the transition state:

"reactions with activation energies of less than 80 kj/mol take place at or below room temperature. reactions with higher activation energies often require heating to give the molecules enough energy to climb the activation barrier." thus, this reaction will not happen at room temperature;...

since entropy is a measure of "disorder" or "randomness" in a system, more small molecules would have more entropy than few large molecules. for example, if you had 40 small molecules in a container, the 40 can rearrange themselves in hundreds of ways within container. if there w...

Enthalpy is a measure of heat content of the system, whereas entropy is the measure of change in (enthalpy/temperature). Enthalpy, H: H=U+PV heat content=internal energy + pressure*volume Entropy,S: deltaS=Q/T change in entropy=heat absorbed/temp essentially entropy measures disorder of molecules. A...

Oxalato is bidentate which is a type of polydentate; if a ligand is polydentate, then bis, tris, tetrakis, etc are used.

A chelate is any metal that is attached to an anion (negatively charged group) with more than one attachment site.

It is a lengthy but doable process to identify a chelating ligand.

UV light has wavelengths from 400 nm to 100 nm, and the given value is 344 nm. Thus it falls in the UV spectrum. Also, to pass a the threshold energy the wavelength must be shorter, not longer, because shorter wavelengths have more energy.

MG: molecular geometry. EPG: electron pair geometry. Molecular geometry deals with the atoms attached to a central atom. Electron pair geometry deals with the atoms and the lone pairs attached to the central atom. Both types are considered zones of electron density, and both types create geometric s...

(3.42) When I first attempted to draw a lewis structure for HCOOH, I put it in a linear structure, i.e. H-C-O-O-H. However, no matter where I put the bonds, I couldn't seem to get the right number of electrons. I had to google the molecule to see that it was H-C-O-H with an additional double bonded ...

I was confused on this topic too.

short wavelengths have more energy, i.e. it has enough energy to "shake" the electron loose. alternatively, a longer wavelength carry less energy. at a certain point, the wavelength becomes too long (not enough energy) to "shake" the electron loose.
