Vedclass · Answer

(C) The structure of diborane $(B_2H_6)$ consists of four terminal hydrogen atoms and two bridging hydrogen atoms.Terminal hydrogen atoms and boron atoms lie in the same plane.It contains two $3$-center-$2$-electron $(3c-2e)$ bonds,often called banana bonds,and four $2$-center-$2$-electron $(2c-2e)$ bonds.It does $NOT$ contain a four-center bond.Therefore,the statement in option $C$ is incorrect.
