A) (i) \[{{B}_{2}}{{H}_{6}}+N{{H}_{3}}/\Delta ,\]at \[-120{}^\circ C\] (ii) Heat at \[200{}^\circ C\]
B) (i) \[LiB{{H}_{4}}+N{{H}_{4}}Cl/\Delta ,\]at \[275{}^\circ C\]
C) (i) \[{{B}_{2}}{{H}_{6}}+N{{H}_{4}}Cl/\Delta ,\]at\[-120{}^\circ C\] (ii) Heat at \[200{}^\circ C\]
D) (i) \[BC{{l}_{3}}+N{{H}_{4}}Cl/\Delta ,\]at \[140{}^\circ C\] (ii) \[NaB{{H}_{4}}\]
Correct Answer: C
Solution :
[c] Statement (3) is INCORRECT (1) (2) \[3LiB{{H}_{4}}+3N{{H}_{4}}Cl\xrightarrow{275{}^\circ C}{{B}_{3}}{{N}_{3}}{{H}_{6}}+3LiCl+9{{H}_{2}}\](3) INCORRECT (4)You need to login to perform this action.
