WebCycloalkanes are very similar to the alkanes in reactivity, except for the very small ones, especially cyclopropane. Cyclopropane is significantly more reactive than what is expected because of the bond angles in the ring. Normally, when carbon forms four single bonds, the bond angles are approximately 109.5°. WebDec 26, 2015 · The product has lesser bond angle strain than the reactant. Hence, the compound formed is stable. This is because s p X 2 hybridised carbonyl carbon requires 120 ∘ but only gets 60 ∘ in cyclopropanone. But …
