Vedclass · Answer

(A) Diborane $(B_2H_6)$ is an electron-deficient molecule. In its structure,the four terminal hydrogen atoms and two boron atoms lie in the same plane. The two bridging hydrogen atoms lie above and below this plane. The terminal $B-H$ bonds are normal $2-$centered$-2-$electron $(2c-2e)$ bonds with a bond angle of $120^{\circ}$ $(x)$. The bridging $B-H-B$ bonds are $3-$centered$-2-$electron $(3c-2e)$ bonds,which are commonly known as banana-bonds or tau-bonds. The bridging $H-B-H$ bond angle $(y)$ is $97^{\circ}$.

The structure of diborane $B_2H_6$ is given below. Identify the bond angles $x, y$. In diborane,which bonds are commonly known as banana-bonds?
