Vedclass · Answer

(C) In $B_2H_6$ (diborane),the two bridging hydrogen atoms are involved in $3c-2e^-$ (three-center two-electron) bonds,also known as banana bonds.$Al_2Cl_6$ and $Fe_2Cl_6$ contain $3c-4e^-$ bonds (due to coordinate bonds from chlorine to metal).$Si_2H_6$ (disilane) contains normal $2c-2e^-$ covalent bonds.Therefore,only $B_2H_6$ contains $3c-2e^-$ bonds.

Which of the following have $3c-2e^-$ bonds?
$I. \ Al_2Cl_6, \ II. \ B_2H_6, \ III. \ Fe_2Cl_6, \ IV. \ Si_2H_6$
