What is the enthalpy change for the isomerization reaction?
\[
\mathrm{CH}_{2}=\mathrm{CH}-\mathrm{CH}_{2}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}_{2} \text { (A) }
\]
\( \stackrel{\mathrm{NaNH}_{2}}{\longrightarrow} \mathrm{CH}_{2}=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH} \)
\[
=\mathrm{CH}-\mathrm{CH}_{3}(\mathrm{~B})
\]
Magnitude of resonance energies of \( \mathrm{A} \) and \( \mathrm{B} \) are 50 and \( 70 \mathrm{~kJ} / \mathrm{mol} \), respectively.
Enthalpies of formation of \( \mathrm{A} \) and \( \mathrm{B} \) are \( -2275.2 \) and \( -2839.2 \mathrm{~kJ} / \mathrm{mol} \), respectively.
(a) \( -584 \mathrm{~kJ} \)
(b) \( -564 \mathrm{~kJ} \)
(c) \( -544 \mathrm{~kJ} \)
(d) \( -20 \mathrm{~kJ} \)
