Question

Oxidation state of nitrogen is correctly given for

	Compound	Oxidation state
(a)	$NH = NH$	$-1$
(b)	$N_{2}O_{3}$	$-3$
(c)	$NH_{2}-NH_{2}$	+2
(d)	$N_{2}O_{4}$	-5

• A. a
• B. b
• C. c
• D. d

Answer 1

Answer: (A)

$N_{2}O_{3} \Rightarrow 2x-6=0$
$\Rightarrow x=+3$
$N_{2}H_{4} \Rightarrow 2x+4=0$
$\Rightarrow x=-2$
$N_{2}O_{4} \Rightarrow 2x-8=0$
$\Rightarrow x=+4$
