Question
Assertion: \[\ce{[Fe(CN)6]^{3-}}\] ion shows magnetic moment corresponding to two unpaired electrons.
Reason: Because it has d2sp3 type hybridisation.
Options
Assertion and reason both are true, reason is correct explanation of assertion.
Assertion and reason both are true but reason is not the correct explanation of assertion.
Assertion is true, reason is false.
Assertion is false, reason is true.

Solution
Assertion is false, reason is true.
Explanation:
The assertion, "\[\ce{Fe(CN)6]^{3-}}\] ion shows magnetic moment corresponding to two unpaired electron" is false as it contains only one unpaired electron only d2sp3 hybridisation, which cannot be regarded as a true reason for its weak paramagnetic behaviour.
