Oxygen will directly react with each of the following elements except?
A.
$$P$$
B.
$$Cl$$
C.
$$Na$$
D.
$$S$$
Answer :
$$Cl$$
Solution :
Out of $$P, Na, S$$ and $$Cl,$$ chlorine does not react directly but $$Na, P$$ and $$S$$ react with oxygen directly.
$$\,{P_4} + 5{O_2} \to {P_4}{O_{10}}$$
$$\,\,\,\,\,S + {O_2} \to S{O_2}$$
$$4Na + {O_2} \to 2N{a_2}O$$
