Q. The expected spin-only magnetic moments (BM) for $[F e (CN)_{6}]^{4 -}$ and $[F e F_{6}]^{3 -}$ respectively are

$1.73$ and $1.73$

$1.73$ and $5.92$

0 and $1.73$

0 and $5.92$

$N$ (unpaired electrons) $= 5$
Magnetic moment $= N (N + 2) BM$
$= 35 BM = 5.92 BM$

Q. The expected spin-only magnetic moments (BM) for [Fe(CN)6​]4− and [FeF6​]3− respectively are

1.73 and 1.73

1.73 and 5.92

0 and 1.73

0 and 5.92
