Which of the following ligand is not responsible for symmetrical bond cleavage in $B_{2} H_{6}$ ?

Options:

Answer:

Solution:

The symmetrical cleavage of diborane ( $B_{2} H_{6}$ ) occurs with ligands that are strong Lewis bases, forming $B H_{3} \cdot L$ adducts. $N H_{3}$ is a strong Lewis base, but it causes unsymmetrical cleavage of $B_{2} H_{6}$ due to the formation of an ionic adduct, $[B H_{2} (N H_{3})_{2}]^{+} [B H_{4}]^{-}$ .

Therefore, $N H_{3}$ is not responsible for symmetrical bond cleavage.
