WebThis reaction involves a mercury (II) compound acting as an electrophile, which is attacked by the alkene double bond to form a mercurinium ion bridge. A water molecule will then attack the more substituted carbon to open the mercurinium ion bridge, followed by proton transfer to a solvent water molecule. WebHere, the formation of a carbocation via attack of the alkene upon H-Br is shown. (Step 1, arrows A and B). Since we have a secondary carbocation adjacent to a tertiary carbon, shift of a hydrogen to the secondary carbocation will result in a (more stable) tertiary carbocation (Step 2, arrow C). do all raven trap thrower parts
