JEE Advance - Chemistry (2009 - Paper 1 Offline - No. 6)
The reaction of P$$_4$$ with X leads selectively to P$$_4$$O$$_6$$. The X is
Dry O$$_2$$.
A mixture of O$$_2$$ and N$$_2$$.
Moist O$$_2$$.
O$$_2$$ in the presence of aqueous NaOH.
Explanation
Phosphorus reacts with limited supply of oxygen to form the given product.
P$$_4$$ + 3O$$_2$$ $$\to$$ P$$_4$$O$$_6$$
N$$_2$$ is used to retard the further oxidation.
