P-Block Elements Ques 587
Question: Among the following compounds, which on heating do not produce $ N_2 $ ?
Options:
A) $ {{(NH_4)}_2}Cr_2{{O}_7} $
B) $ NH_4Cl+NaNO_2 $
C) $ NH_4Cl+CaO $
D) $ Ba{{(N_3)}_2} $
Show Answer
Answer:
Correct Answer: C
Solution:
[a] $ {{(NH_4)}_2}Cr_2O_7\xrightarrow{\Delta }Cr_2O_7+N_2+H_2O $ [b] $ NH_4Cl+NaNO_2\xrightarrow{\Delta }NH_4NO_2+NaCl $ [c] $ 2NH_4Cl+CaO\xrightarrow{\Delta }CaCl_2+2NH_3\uparrow +H_2O $ [d] $ NH_4NO_2\xrightarrow{\Delta }N_2\uparrow +2H_2O $ $ Ba{{(N_3)}_2}\xrightarrow{\Delta }Ba+3N_2\downarrow $
