Vedclass · Answer

(C) Among the alkali metals $(Group \ 1)$,only $Li$ reacts with atmospheric nitrogen to form a nitride $(Li_3N)$.All alkaline earth metals $(Group \ 2)$ react with nitrogen to form nitrides.When these nitrides react with moisture $(H_2O)$,they release ammonia $(NH_3)$ gas,which has a characteristic pungent smell.$1. \ Mg + N_2 	o Mg_3N_2 \xrightarrow{H_2O} Mg(OH)_2 + NH_3$$2. \ Ca + N_2 	o Ca_3N_2 \xrightarrow{H_2O} Ca(OH)_2 + NH_3$$3. \ Li + N_2 	o Li_3N \xrightarrow{H_2O} LiOH + NH_3$$4. \ K + N_2 	o 	ext{No reaction}$Since $K$ does not form a nitride,it does not release ammonia upon exposure to moist air.

List-$I$	List-$II$
$(a)$ $Li$	$(i)$ Poor water solubility of $I^{-}$ salt
$(b)$ $Na$	$(ii)$ Most abundant element in cell fluid
$(c)$ $K$	$(iii)$ Bicarbonate salt used in fire extinguisher
$(d)$ $Cs$	$(iv)$ Carbonate salt decomposes easily on heating

Which of the following metals,upon burning in moist air,does not produce the smell of ammonia?
