Reactivity of alkene |
Answer» Solution :In alkene, carbon-carbon has weak `pi`-bond.  Electrons of `pi`-bonds shows weak dynamic electrons. This type of `pi`-electrons source is present in alkene. So such type of REACTANT and COMPOUNDS attack on `pi`-bond and alkene and break `pi`-bond easily and FORMS compounds having single bond. So alkane compounds easily gives addition reaction. `pi`-bond because alkene is more reactive and less stable than alkanes. So, STRENGTH of C-C in alkane (bond ethalpy `384 kJ mol^(-1)`), is less then strength of C-C in alkene (bond enthalpy 681 kJ/mol). |
