Vedclass · Answer

(A) In the structure of diborane $(B_2H_6)$, there are two boron atoms.Each boron atom is bonded to two terminal hydrogen atoms via normal covalent bonds ($2 	imes 2 = 4$ terminal hydrogens).The two boron atoms are linked by two bridging hydrogen atoms, which form $3c-2e$ (three-center two-electron) bonds.Therefore, there are $4$ terminal hydrogens and $2$ bridging hydrogens.

The number of terminal and bridging hydrogens in $B_2H_6$ are respectively
