Indicate whether the pair of structures shown represent stereoisomers, constitutional isomers, different conformations of the same compound, or the same conformation of a compound viewed from a different perspective. Note that cis, trans isomers are an example of stereoisomers. H3C. H3C Br Br OCH3 H3C- H3C. LOCH3

Ma Two disubstituted cyclohexane molecules are depicted. Classify the pair as the same compound, enantiomers, diastereomers, constitutional isomers, or not isomeric. CI CI and CI The compounds are: the same compound not isomeric diastereomers enantiomers constitutional isomers CI

We have learned that isomers (molecules with the same molecular formula) can have different relationships, and these relationships can be made more clear by comparing IUPAC names. Constitutional isomers will differ in the main part of the name. Stereoisomers will differ only in the stereochemical prefix part of the name (cis/trans). Conformational isomers will actually have the same name, but different energies. Two structures that have the same names and the same energies are identical. What is the relationship between these two structures?

Caculate ℰ° values for the following cells. Which reactions are spontaneous as written (under standard conditions)? Balance the equations. Standard reduction potentials are found in the Standard Reduction Potentials table. (Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.)

Classify each pair of compounds as constitutional (structural) isomers or stereo isomers
