Vedclass · Answer

(D) Alkali metal salts impart characteristic colors to the flame due to the excitation of electrons to higher energy levels and their subsequent return to the ground state.The characteristic wavelengths for these metals are:$Li$: $670.8 	ext{ nm}$ (Crimson Red)$Na$: $589.2 	ext{ nm}$ (Yellow)$Rb$: $780.0 	ext{ nm}$ (Red-violet)$Cs$: $455.5 	ext{ nm}$ (Blue)Therefore,the correct matching is: $(a)-(ii), (b)-(iv), (c)-(iii), (d)-(i)$.

List-$I$ (Salt)	List-$II$ (Flame colour wavelength)
$(a)$ $LiCl$	$(i)$ $455.5 \text{ nm}$
$(b)$ $NaCl$	$(ii)$ $670.8 \text{ nm}$
$(c)$ $RbCl$	$(iii)$ $780.0 \text{ nm}$
$(d)$ $CsCl$	$(iv)$ $589.2 \text{ nm}$

Match List-$I$ with List-$II$:

List-$I$ (Salt) List-$II$ (Flame colour wavelength)

$(a)$ $LiCl$ $(i)$ $455.5 \text{ nm}$

$(b)$ $NaCl$ $(ii)$ $670.8 \text{ nm}$

$(c)$ $RbCl$ $(iii)$ $780.0 \text{ nm}$

$(d)$ $CsCl$ $(iv)$ $589.2 \text{ nm}$
