n= 4 because you must determine the oxidation numbers of each molecule in the reaction. 2 Fe has a oxidation number of 0, 2 H2O has an overall charge of 0 (2H=1+, O=2-), and O2 is also 0. Fe(OH)2 has an overall charge of 0 but the 2 OH groups have a 1- charge and so Fe must be 2+. The oxidation stat...

Why is the compound 1,5,5,6-tetramethylcyclohex-1-ene not named 2,3,4,4-tetramethylcyclohex-1-ene? Wouldn't the overall numbering of the second one be lower than the first except for the the first substituent?

Its not optional because in this case you have two substituents and by not labeling it with a 1, it is ambiguous where the ethyl is located.

A torsional strain is the repulsion caused by the electrons in between different groups when they pass by each other. A steric strain is caused by the electrons in between different groups. Steric strain cannot be lessened by rotating the molecule around a bond. An angle strain is caused when the ac...

If a nucleophile has a negative charge not a partial negative charge, the more negative the charge is, the stronger the nucleophile. After will come the nucleophiles with partial negative charges due to difference in electronegativity, last will be nucleophiles with the lone pairs or double bonds pr...

If its not given, you can easily solve for it by taking the ln of the Arrhenius equation which will give you ln k= -Ea/RT + lnA which follows y=mx+b so your slope would just be -Ea/R if the x-axis is 1/T.

Electrophiles are missing electrons so they are attracted to positive charges while ucleophiles more negative and have more electrons so they will have negative charges. You can remember that bases are nucleophiles and all acids are electrophiles.

You will need an inert conductor when the solution is comprised of only ions and no solid metals. For example, Zn(s) + Cu2+ → Zn2+ + Cu(s) does not need an inert conductor because each side of the electrode solution has a metal, but if either the reactants or the product's had two aqueous compounds ...

H3O+ and OH- are also both related acid base reactions. A base will form OH- while an acid will form H3O+. Both reactions for acids and bases will start out with either a base or acid and H2O. The H3O+ and OH- is formed as a product from the H2O in both cases.

CH3COOH + H2O -> CH3COO- + H3O+ Is the equation for this dissociation. The Ka value will either be given or you have to find it. You can find the amount of the product that is dissociated using the Ka value that would be given in this case it is 1.8× 10–5 M. You will use [CH3COO-][H3O+]/[CH3COOH]=Ka...

A ligand is the molecule that will donate a lone pair to the central metal ion in a coordinate compound.

Denticity is basically number bonds they can form with the metal ion. A ligand will be bidentate if it can make two bonds with the metal ion and tridentate if it can form three. You can tell a ligand will be mono-, bi-, or tri- dentate by looking at the number of atoms that can donate an electron pa...
