5. Given the bond dissociation energies below (in kcal/mol), calculate the overall AH° for the following reaction: (CH3);CH + Br2 (CH3);C-H (CH3);C-Br (CH3)3CB + HBr 91 65 Br-Br 46 Н-Br 88 СН3-Br 70 6. Consider the reaction: CH3CH2· + Br2 → CH3CH2Br+ Br·. Given that this reaction has activation energy of +6 kcal/mol and a AH° of -22 kcal/mol, sketch a reaction-energy diagram for this reaction. Label the axes and show Ea and AH° on your drawing.

The diasteromers of 4-t-butylcyclohexanol that you make can be distinguished by the splitting patterns of the proton attached to the carbon bearing th OH group. This is due to the fact that the H that is axial is a triplet of triplets because it is coupled to to sets of non-eqivalent protons, while the equatorial H is coupled to 4 equivalent hydrogens and is a pentet.

The crocodile, which can remain under water without breathing for up to 1 h, drowns its air-breathing prey and then dines at its leisure. An adaptation that aids the crocodile in doing so it that it can utilize virtually 100% of the O2in its blood whereas humans, for example, can extract only ~65% of the O2in their blood. Crocodile Hb does not bind BPG. However, crocodile deoxyHb preferentially binds HCO3ꟷ. How does this help crocodile obtain its dinner? Explain your answer.
