Fe^(3+)overset(SCN^(-) ("excess"))rarr "...

`Fe^(3+)overset(SCN^(-) ("excess"))rarr "Blood red (A)" overset(F^(-)("excess"))rarr "Colourless (B)"`
Identify A and B.
(i) Write IUPAC name of A and B.
(ii) Find out spin only magnetic moment of B.

Text Solution

Verified by Experts

The correct Answer is:
`A=[Fe(SCN)(H_(2)O)_(5)]^(2+), M M=sqrt(35)`
Pentaaquathiocynanato-S-iron (III) iron
`B=[FeF_(6)]^(3-), M M=sqrt(35)`
hexaflouroferrate (III) ion
