Question

Assertion When NO reacts with $FeSO _{4}$, a brown coloured complex is formed.
Reason In the complex, the coordination number of Fe is $+6$.

• A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
• B. If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion
• C. If Assertion is true but Reason is false
• D. If both Assertion and Reason are false

Answer 1

Answer: (B)

$FeSO _{4}$, when reacts with $NO$, a brown colour complex, called ferrous nitroso sulphate is formed.
$FeSO _{4}+ NO \xrightarrow{ H _{2} O }\left[ Fe ( OH )_{5} NO \right] SO _{4}$
In this complex, the coordination number of $Fe$ is $6 $ .
