Solution
Diborane (), when treated with Lewis base, undergoes cleavage or bond-breaking to form Borane () addition products. For example-
The reaction of diborane with Lewis base Ammonia occurs in two steps. i) Ammonia reacts with diborane forming whose ionic form is . ii) When is further heated, it gives Borazine, () with the elimination of Hydrogen from the Lewis base.
Therefore, Diborane reacts with Lewis base, forming Borane addition products by undergoing cleavage.
