JEE Main
JEE Main 2014
Coordination Compounds
A
$Li_2O+2KCl \rightarrow 2LiCl+K_2O $
20%
B
$[CoCl(NH_3)_5]^+ \, +5H^+ \rightarrow Co^{2+}+5NH_4^+ + Cl^- $
40%
C
$\left[ Mg \left( H _{2} O \right)_{6}\right]^{2+}+( EDTA )^{4-} \xrightarrow{\text { excess } NaOH }[ Mg ( EDTA )]^{2+}+6 H _{2} O$
21%
D
$CuSO_4+4KCN \rightarrow K_2[Cu(CN)_4]+K_2SO_4 $
19%
Solution:
The complex
$\left[ CoCl \left( NH _{3}\right)_{5}\right]^{+}$ decomposes under acidic medium, so $\left[ CoCl \left( NH _{3}\right)_{5}\right]^{+}+5 H ^{+} \rightarrow Co ^{2+}+5 NH _{4}^{+}+ Cl ^{-}$
