Chemistry - Aromatic Hydrocarbon Question with Solution | TestHub

In lsomers of Hydrocarbon heat of combustion depends upon their stability. As stability increases, heat of combustion decreases.
trans-alkenes are more stable than cis-alkenes
Stability$\propto \frac{1}{\mathrm{H}\mathrm{e}\mathrm{a}\mathrm{t}\text{ of combustion}}$
Stability$\mathrm{a}>\mathrm{b}>\mathrm{c}$
Heat of combustion$\mathrm{c}>\mathrm{b}>\mathrm{a}$
