Can someone list Alkynes, Alkanes, and Alkenes in order of greatest to least reactivity?
Alkene > Alkyne > Alkane Alkanes show a relatively low reactivity, because their C bonds are relatively stable and cannot be easily broken. It has sigma bonds. There are 3 bonds in Alkyne. 1 of them is a sigma bond and the 2 other bonds are pi bonds. Though usually compounds with pi bonds have a greater reactivity, in this case the pi bonds make a 3D disturbance so that bond cannot be easily broken. Alkene has the greatest reactivity because there is only one sigma bond and one pi bond. Both alkene and alkyne reacts with Br2 (l), H2SO4/KMnO4(aq) proving that they have double bonds.
