These questions consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses:
Assertion: `[Fe(CN)_6]^(3-)` has `d^2sp^3` type hybridisation.
Reason: `[Fe(CN)_6]^(3-)` ion shows magnetic moment corresponding to two unpaired electrons.

A

(a) If both the assertion and reason are true and reason is a true explanation of the assertion.

B

(b) If both the assertion and reason are true but the reason is not the correct explanation of assertion.

C

(c) If the assertion is true but reason is false.

D

(d) If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
`Fe^(3+)[Ar]^(18)3d^5`
Forced pairing caused by `CN^(-)`

has 1 unpaired electron.
