Consider the following reactions. I. {Na}_{2} {B}_{4} {O}_{7} \stackrel{760{ }{ ─\xrightarrow^{\circ} {C}} {A}+ {B}_{2} {O}_{3} II. {Si}+ {KOH}+ {H}_{2} {O} \rightarrow {B}+ {H}_{2} ↑ III. {P}_{2} {O}_{5}+ {HNO}_{3} \rightarrow {HPO}_{3}+ {C} IV. {NH}_{3}+ {Cl}_{2} (excess) \rightarrowD+ {HCl} Identify the missing products (A, B, C and D) of the given reactions.

Correct Answer is : (A)→NaBO2(B)→K2SiO3(C)→N2O5(D)→NCl3

(A)\to{Na}_{2} {O} (B)\to {KSiO}_{3} (C)\to {N}_{2} {O}_{4} (D)\to {NCl}_{3}

(A)\to{NaBO}_{2} (B)\to {K}_{2} {SiO}_{3} (C)\to {N}_{2} {O}_{5} (D)\to {NCl}_{3}

(A)\to {NaBO}_{2} (B)\to{K}_{2} {SiO}_{3} (C)\to {N}_{2} {O}_{4} (D)\to{ } { {N^{⊕}Cl}_{4}}

(A)\to{Na}_{2} {O} (B)\to {K}_{2} {SiO}_{3} (C)\to {N}_{2} {O}_{5} (D)\to {NCl}_{3}
