The correct order of the oxidation states of nitrogen in N O , N 2 O , N O 2 and N 2 O 3 is

Options

AN 2 O < N O < N 2 O 3 < N O 2
BN O 2 < N 2 O 3 < N O < N 2 O
CN O 2 < N O < N 2 O 3 < N 2 O
DN 2 O < N 2 O 3 < N O < N O 2

Correct answer

A. N 2 O < N O < N 2 O 3 < N O 2

Step-by-step solution

Oxidation states of following N 2 O ⇒ 2 x + 1 - 2 = 0 ⇒ x = 1 N O ⇒ x + 1 - 2 = 0 ⇒ x = 2 N 2 O 3 ⇒ 2 x + 3 - 2 = 0 ⇒ x = 3 N O 2 ⇒ x + 2 - 2 = 0 ⇒ x = 4
