MCQ
Which of the following complexes has maximum $CFSE$?
- ✓$K _{3}\left[ Fe ( CN )_{6}\right]$
- B$K _{3}\left[ Co ( Ox )_{3}\right]$
- C$K _{3}\left[ CoF _{6}\right]$
- D$K _{3}\left[ Co ( CN )_{6}\right]$
$-2.0 \Delta_{0}$
So, $K _{3}\left[ Fe ( CN )_{6}\right]$ has maximum $CFSE.$

$BF _{3}+ NaH \stackrel{450 K }{\longrightarrow} A + NaF$
$A + NMe _{3} \rightarrow B$
$A\, \rightleftharpoons \,B$ ${K_C} = 2$
$B\, \rightleftharpoons \,C$ ${K_C} = 3$
$C\, \rightleftharpoons \,D+E$ ${K_C} = 5$
$K_C$ for the reaction $A\, \rightleftharpoons \,D+E$ is
