how to calculate change in energy (ΔG) |
|
Definition
ΔG = ΔH - TΔS
ΔG = change in energy ΔH = change in enthalpy T = temp in K ΔS = change in entropy |
|
|
Term
|
Definition
if there's less entropy on products than on reactants |
|
|
Term
relationship between temp and ΔG |
|
Definition
increasing temp causes ΔG to become less negative, thus rxn less spontaneous |

Term
polarizability basically means... |
|
Definition

|
|
Term
why the intermediate step of the rxn of an alkene with Cl2 contains a Cl atom with 2 bonds to that alkene |
|
Definition
keeps us from disobeying octet rule |
|
|
Term
how to calculate the rate of a rxn |
|
Definition
rate = k[reactant 1][reactant 2]...[reactant x] |
|
|
Term
why the Br in a rxn of an alkene with Br2 could prefer 1 partially positive C over another |
|
Definition
because 1 C could be more stable than the other |
|
|
Term
example of how deuterium is incorporated into the nomenclature of a molecule |
|
Definition
2-deutero-1-methylcyclopentene |
|
|
Term
why a cycloalkene acquires only 1 Br when there's water involved in the reaction |
|
Definition
because water blocks the addition of another Br |
|
