You Are Given Pure Samples of Pentane $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{3}(l)$

You are given pure samples of pentane, $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{3}(l)$ , and 1,3-pentadiene, $\mathrm{CH}_{2}=\mathrm{CHCH}=\mathrm{CHCH}_{3}(l)$ What prediction would you make concerning their standard molar entropies at 298 K?

A) S $\degree$ _pentane > S $\degree$ _{1,3-pentadiene}
B) S $\degree$ _pentane < S $\degree$ _{1,3-pentadiene}
C) S $\degree$ _pentane $\approx$ S $\degree$ _{1,3-pentadiene}
D) S $\degree$ _pentane  S $\degree$ _{1,3-pentadiene} + 2*
E) More information is needed to make reasonable predictions.
