(i) Fe3+ + 3SCN- longrightarrow underset AFe(SCN)3 (blood red colouration) Fe(SCN)3 + F- text(excess) longrightarrow underset B[FeF6]3- + 3SCN- (ii) Magnetic moment (μS) = √n(n + 2) BM =√35 BM = 5.92 BM.

Q. $F e^{3 +} SC N^{-} (excess)$ Blood red $(A) F^{-} (e x cess)$ Colourless $(B)$
Identify $A$ and $B$ .
(i) Write IUPAC name of $A$ and $B$ .
(ii) Find out spin only magnetic moment of $B$ .

(i) $F e^{3 +} + 3 SC N^{-} ⟶ A F e (SCN)_{3}$ (blood red colouration)
$F e (SCN)_{3} + F^{-} (excess) ⟶ B [F e F_{6}]^{3 -} + 3 SC N^{-}$
(ii) Magnetic moment $(μ_{S}) = n (n + 2) BM$
$= 35 BM = 5.92 BM .$

Q. Fe3+SCN−(excess)​ Blood red (A)F−(excess)​ Colourless (B) Identify A and B. (i) Write IUPAC name of A and B. (ii) Find out spin only magnetic moment of B.

(i) Fe3++3SCN−⟶AFe(SCN)3​​ (blood red colouration) Fe(SCN)3​+F−(excess)⟶B[FeF6​]3−​+3SCN− (ii) Magnetic moment (μS​)=n(n+2)​BM =35​BM=5.92BM.
