Cyclopropane bond length
WebCycloalkanes are very similar to the alkanes in reactivity, except for the very small cycloalkanes, especially cyclopropane. Cyclopropane is much 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°. WebThe CYCLOPROPANE molecule contains a total of 9 bond (s) There are 3 non-H bond (s) and 1 three-membered ring (s).

In my exam, I was asked why cyclopropane could decolourise bromine water (indicating that it reacted with the bromine). All I could guess was that it is related to the high angle strain in cyclopropane, as the C–C–C bond angle is 60 ∘ instead of the required 109.5 ∘. No book I have read mentions this reaction.
