Question

Diborane ($B_2H_6$) undergoes cleavage reactions with Lewis bases. Which of the following bases will cause symmetrical cleavage of diborane to form an $L \rightarrow BH_3$ adduct?

Answer: D

💡 Solution & Explanation

Diborane undergoes asymmetrical cleavage with small, unhindered bases like $NH_3$, $CH_3NH_2$, and $(CH_3)_2NH$ to form ionic products. However, large bulky amines such as $(CH_3)_3N$ and pyridine induce symmetrical cleavage, forming $L \rightarrow BH_3$ adducts.
