Q. The incorrect statement regarding $'X'$ in given reaction is :

$BF_{3}+LiAlH_{4}\overset{E t h e r}{ \rightarrow }\left(X\right)+LiF+AlF_{3}$

NTA AbhyasNTA Abhyas 2020The p-Block Elements - Part2

Solution:

Here X is $B_{2}H_{6}$ and statement A, B and C are correct. only D is incorrect as it can react with ammonia

$BF_{3}+LiAlH_{4}\overset{E t h e r}{ \rightarrow }B_{2}H_{6} \\ \left(\right.X\left.\right)+LiF+AlF_{3}$

$NH_{3}$ can react with $B_{2}H_{6}$

$B_{2}H_{6}+2NH_{3}\overset{w a r m}{ \rightarrow }\left[\right.BH_{2}.2NH_{3}\left]\right.^{+}.\left[\right.BH_{4}\left]\right.^{-}\overset{200 ^\circ C}{ \rightarrow }B_{3}N_{3}H_{6}$ (Inorganic benzene)
