Match Column $-I$ with Column $-II$.

Column $-I$	Column $-II$
$(A).$ Dumas method	$(3).$ Nitrogen gas
$(B).$ Kjeldahl's method	$(5).$ Ammonium sulphate
$(C).$ Carius method	$(1).$ $AgNO_3$
$(D).$ Chromatography	$(2).$ Silica gel
$(E).$ Homolytic fission	$(4).$ Free radical

(A-3, B-5, C-1, D-2, E-4) The correct matching is: $A-3, B-5, C-1, D-2, E-4$.
$(A).$ Dumas method: In this method,nitrogen is estimated as nitrogen gas $(N_2)$.
$(B).$ Kjeldahl's method: In this method,nitrogen is converted into ammonium sulphate $((NH_4)_2SO_4)$.
$(C).$ Carius method: This method is used for the estimation of halogens,where the compound is heated with $AgNO_3$ in the presence of $HNO_3$.
$(D).$ Chromatography: In thin layer chromatography,a thin layer $(0.2 \ mm)$ of an adsorbent such as silica gel is spread over a glass plate,which acts as a stationary phase.
$(E).$ Homolytic fission: When the homolytic fission of a covalent bond occurs,free radicals are formed.
