The carbocation is often shaped on possibly aspect with the double bond depending on the groups hooked up to its ends, and the preferred configuration can be predicted Along with the Markovnikov's rule.[53] This rule states that "While in the heterolytic addition of a polar molecule to an alkene or alkyne, the more electronegative (nucleophilic) atom (or portion) in the polar molecule becomes connected towards the carbon atom bearing the smaller sized range of hydrogen atoms."[54]
In 1774, the scientist Joseph Priestley turned his curiosity to some mineral called cinnabar – a brick crimson mineral.
