In diborane,${\text{(B}}_{\text{2}}{\text{H}}_{\text{6}}\text{)}$molecule, only four terminal hydrogen atoms are replaceable. The two bridge$\text{H}$-atoms cannot be substituted. Hence${\text{B}}_{\text{2}}{{\text{(CH}}_{\text{3}}\text{)}}_{\text{6}}$cannot be prepared from${\text{B}}_{\text{2}}{\text{H}}_{\text{6}}.$
