Vedclass · Answer

(A) The reaction of diborane $(B_2H_6)$ with terminal alkenes is known as hydroboration-oxidation. In the first step,the alkene undergoes hydroboration to form a trialkylborane. In the second step,the trialkylborane reacts with alkaline hydrogen peroxide $(H_2O_2/OH^-)$ to undergo oxidation. This process results in the anti-Markovnikov addition of water across the double bond,yielding a primary alcohol as the major product.

Diborane reacts with terminal alkenes to form trialkylboranes. These react with alkaline hydrogen peroxide to form:
