WebBond lengths vary considerably with structure and depend on the identity of both atoms, the type of bonding (single, double, or triple), and the nature of other atoms or groups … WebMay 12, 2014 · Viewed 20k times. 46. 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.

WebWe can calculate the bond angles for these regular polyhedrons if they were flat, that is, two-dimensional: they would range from 60° for cyclopropane to 120° for cyclohexane, both far outside the range of sp 3 bond angles. WebCyclopropane is further destabilized by the torsional strain that results from having three eclipsed C―H bonds above the plane of the ring and three below.

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°.
