Question

Assertion :EAN of Fe in ferrocene is 36. Reason: $6\pi e^{-}$ are co-ordinated by each cyto pentadien ring with central metal ion.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Assertion is incorrect but Reason is correct

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Ferrocene is an organometallic compound with the formula $Fe(C_5{H}_5{)}_2$. It is the prototypical metallocene in which $6\pi e^{-}$ are co-ordinated by each cyto pentadien ring with the central metal ion.

Atomic no. of iron is 26 and its oxidation number in the complex is +2.

EAN $=[26-2]+2\times 6$

$=36$
