Vedclass · Answer

(D) The structure of diborane $(B_2H_6)$ consists of two terminal $BH_2$ groups and two bridging hydrogen atoms.In this structure, there are two types of $B-H$ bonds:$1$. Terminal $B-H$ bonds: These are normal $2c-2e$ (two-center, two-electron) covalent bonds.$2$. Bridging $B-H-B$ bonds: These are $3c-2e$ (three-center, two-electron) bonds, also known as banana bonds.Since the terminal and bridging bonds have different bond lengths ($119 \ pm$ and $134 \ pm$ respectively) and different bonding characteristics, the statement that all $B-H$ bonds are similar is incorrect.Therefore, the correct option is $D$.

Identify the statement that is not correct as far as the structure of diborane is concerned.
