Question
On heating compound (A) gives a gas (B) which is constituent of air. The gas when treated with H2 in the presence of catalyst gives another gas (C) which is basic in nature, (A) should not be ______.
Options
(NH4)2Cr2O7
NH4NO2
Pb(NO3)2
NaN3
Solution
On heating compound (A) gives a gas (B) which is constituent of air. The gas when treated with H2 in the presence of catalyst gives another gas (C) which is basic in nature, (A) should not be Pb(NO3)2.
Explanation:
(NH4)2Cr2O7, NH4NO2, NaN3 on heating gives N2 gas which is present in the air in 77.16% by volume. N2 on reaction with H2 in the presence of catalyst gives ammonia (NH3) which basic in character. But Pb(NO3)2 on heating produces brown-coloured NO2 gas as well as oxygen gas.
\[\ce{2Pb(NO3)2 ->[\Delta] 2PbO + 4NO2 + O2 ^}\]
