Cyclopropane and bromine
Did you know?
WebJul 10, 2024 · Cyclopropane is an alkane and will react with bromine to undergo bromination via a free radical mechanism. This mechanism involves 3 steps: Initiation, propogating and terminating. The product in this case would be bromocylcopropane. Web8 years ago Why does cyclopropane react with bromine? 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 $60^\circ$ instead of the required $109.5^\circ$.
WebYes, NO₂ is more deactivating than Br, but you can compensate for this by raising the temperature. There are many factors that affect yield. For example, bromination of … WebCycloalkanes have one or more rings of carbon atoms. The simplest examples of this class consist of a single, unsubstituted carbon ring, and these form a homologous series similar to the unbranched alkanes. The IUPAC names of the first five members of this series are given in the following table.
