Due to steric hinderence, hyperconjugation and heat of hydrogenation, reactivity of alkenes can be shown as: $$\begin{array}{rl}& {\mathrm{H}}_2\mathrm{C}={\mathrm{CH}}_2>\mathrm{R}-\mathrm{CH}={\mathrm{CH}}_2>\\ & \mathrm{R}-\mathrm{CH}=\mathrm{CH}-\mathrm{R}>{\mathrm{R}}_2\mathrm{C}={\mathrm{CH}}_2>\\ & {\mathrm{R}}_2\mathrm{C}=\mathrm{CHR}>{\mathrm{R}}_2\mathrm{C}={\mathrm{CR}}_2.\end{array}$$ Related Theory The relative rates of hydrogenation decrease with the increase of steric hindrance. In order of stability of alkene, most stable the alkene slowly it gives the product.
