WebPage 6 : , , A carbocation is an organic species, an intermediate, that, forms as a result of the loss of two valence electrons,, normally shared electrons, from a carbon atom that already, , has four bonds., , , This leads to the formation of a carbon atom bearing a, , positive charge and three bonds instead of four. WebThe carbocation formation occurs when the leaving group is lost from the site. Dehydration of alcohols: The hydroxyl group (OH) acts as the leaving group, forming a carbocation. The carbocation undergoes a 1,2-hydride shift to form a highly stable tertiary carbocation intermediate. Alkene is formed in the final step. stashh invercargillWebSince a tertiary carbocation is bonded with 3 other alkyl groups, the electrons on the hydrogens of the alkyl groups stabilize the positive charge.
