Alkene Hydration: Water and 4-methyl-2-pentene.
In an experiment you combine 4-methyl-2-pentene and water, in the lab you setup the experiment using a a heater, condenser and N2 gas and add the reagent H2SO4, the product formed is 2-methyl-2-pentanol. Which molecular species would be necessary for the formation of the product in the reaction; a primary carbocation, a tertiary carbocation, a primary carbanion, a secondary carbanion or SO4?
