WebJan 23, 2024 · In the presence of UV light, cyclopropane will undergo substitution reactions with chlorine or bromine just like a non-cyclic alkane. However, it also has the ability to react in the dark. In the absence of UV light, cyclopropane can undergo addition reactions in which the ring is broken. WebBromination of alkanes has close similarities to chlorination except the rate of reaction is slow. Fluorination of alkane is so violent that it results in the cleavage of C - C as well as C - H bonds. Reactivity of X2 : F2 > Cl2 > Br2 > I2 Halogenations Reactivity Selectivity Principle : In more complex alkanes, the abstraction of each
WebJan 23, 2024 · Step 1: Initiation Once the pre-initiation step involving NBS produces small quantities of Br 2, the bromine molecules are homolytically cleaved by light to produce bromine radicals. Step 2: Propagation One bromine radical produced by homolytic cleavage in the initiation step removes an allylic hydrogen of the alkene molecule.
