WebIn step 1, the C—Br bond breaks and Br departs with the bonding electron pair to produce a tertiary carbocation and bromide anion Br –.This step only involves a highly endothermic bond-breaking process, and this is the slowest step in the whole mechanism. In the multiple-step mechanism, the overall reaction rate is determined by the slowest step, and such a … WebThe cycloalkanes have the general formula \ ( {C_n} {H_ {2n}}\).

WebReactions of Cycloalkanes Halogenation of cycloalkanes occurs in the presence of heat or light to form a halogenated cycloalkane. Ring opening of cyclopropane occurs with hydrogen halide to form 1-halopropane. Ring opening of cyclopropane occurs with halogen to give 1,3-dichloropropane. Ring opening of cyclopropane occurs with hydrogen to ... The simple and the bigger cycloalkanes are very stable, like alkanes, and their reactions, for example, radical chain reactions, are like alkanes. The small cycloalkanes – in particular, cyclopropane – have a lower stability due to Baeyer strain and ring strain. They react similarly to alkenes, though they do not react in electrophilic addition, but in nucleophilic aliphatic substitution. These reactions are ring-opening reactions or ring-cleav…
