WebFeb 15, 2013 · This study was undertaken in order to rationalize the peculiar (1)H NMR chemical shifts of cyclopropane (δ 0.22) and cyclobutane (δ 1.98) which are shifted upfield and downfield with respect to larger cycloalkanes (δ 1.44-1.54). This is conventionally accounted for by shielding contributions arising … 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.
