Due to steric hinderence, hyperconjugation and heat of hydrogenation, reactivity of alkenes can be shown as: H2C=CH2>R−CH=CH2>R−CH=CH−R>R2C=CH2>R2C=CHR>R2C=CR2. 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.
