प्रश्न
Assertion: \[\ce{[Fe(CN)6]^{3-}}\] ion shows magnetic moment corresponding to two unpaired electrons.
Reason: Because it has d2sp3 type hybridisation.
विकल्प

उत्तर
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.
