Q. Two oxides of nitrogen NO and NO_{2} react together at 253${^\circ}$K and form a compound of nitrogen X. X reacts with water to yield another compound of nitrogen Y. The shape of the anion of Y molecule is
A) Tetrahedral
B) Triangular planar
C) Square planar
D) Pyramidal
Explanation
(b)
NO+NO_{2}$\overset{253℃}{\rightarrow}$N_{2}O_{3}
(X)
N_{2}O_{3}+H_{2}O⟶2HNO_{2}
(X) (Y)
$\therefore\$Anion of y is ${NO}_{2}^{-}$
[image:7_image35.emf] Its shape is triangular planar.
