प्रश्न

Assertion: \[\ce{[Fe(CN)6]^{3-}}\] ion shows magnetic moment corresponding to two unpaired electrons.

Reason: Because it has d2sp3 type hybridisation.

विकल्प

  • 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.

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.
