Consider the two conformers of butane below. If \( \mathrm{H} \cdot \mathrm{H} \) eclipses are \( 4 \mathrm{~kJ} / \mathrm{mol} \) each and the conformer on the left is 19 \( \mathrm{kJ} / \mathrm{mol} \) higher in energy than the conformer on the right, what is the value for each \( \mathrm{CH}_{3}-\mathrm{CH}_{3} \) eclipse? a) \( 11 \mathrm{~kJ} / \mathrm{mol} \) b) \( 6 \mathrm{~kJ} / \mathrm{mol} \) of \( 19 \mathrm{~kJ} / \mathrm{mol} \) (d) \( 4 \mathrm{~kJ} / \mathrm{mol} \mathrm{A} \) 20. Consider the reaction below. Which side does the equilibrium favor? \[ \Rightarrow \] a) the right because the tert-butyl group is in the axial position b) the right because the tert-butyl group is in the equatorial position c) the left because the tert-butyl group is in the axial position (d) the left because the tert-butyl group is in the equatorial position 23. Name the following molecules 24. Calculate \( \Delta H^{\circ} \) xn for the following reaction given the following bond dissociation energies. \[ \mathrm{CH}_{3} \mathrm{CHCH}_{2}+\underset{\mathrm{Br}}{2} \stackrel{\text { light }}{\longrightarrow} \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{Br}+\mathrm{HBr} \]
