Chemistry Question on Haloalkanes and Haloarenes
A solution of colourless unknown salt (X) on boiling with excess of NaOH produces non-flammable gas. The gas evolution ceases after some time. Upon addition of Zn dust to the same solution, the gas evolution restarts. The colourless salt (X) is (are)
A
(A) NH4NO3
B
(B) (NH4)2SO4
C
(C) NH4NO2
D
(D) NH4Cl
Answer
(B) (NH4)2SO4
Explanation
Solution
Explanation:
NH4X+NaOH→NaX+H2O+NH3↑(X=NO3−,NO2−,Cl−,SO42−)
