Question

Identify the incorrect statement among the following

A. $$B{r_2}$$  reacts with hot and strong $$NaOH$$  solution to give $$NaBr$$  and $${H_2}O.$$
B. Ozone reacts with $$S{O_2}$$  to give $$S{O_3}.$$
C. Silicon reacts with $$NaOH(aq)$$   in the presence of air to give $$N{a_2}Si{O_3}$$   and $${H_2}O.$$
D. $$C{l_2}$$  reacts with excess of $$N{H_3}$$  to give $${N_2}$$  and $$HCl.$$  
Answer :   $$C{l_2}$$  reacts with excess of $$N{H_3}$$  to give $${N_2}$$  and $$HCl.$$
Solution :
Chlorine reacts with excess of ammonia to produce ammonium chloride and nitrogen. $$3C{l_2} + 8N{H_3}\left( {{\text{excess}}} \right) \to 6N{H_4}Cl + {N_2}$$
