A coordination compound X gives pale yellow colour with AgNO3 solution while its isomer Y gives white precipitate with BaCl2. Two compounds are isomers of CoBrSO4⋅ 5NH3. What could be the possible formula of X and Y ?

Question

A coordination compound X gives pale yellow colour with AgNO3 solution while its isomer Y gives white precipitate with BaCl2. Two compounds are isomers of CoBrSO4⋅ 5NH3. What could be the possible formula of X and Y ? (A) X=[Co(NH3)5SO4] Br, Y= [Co(NH3)5 Br] SO4 (B) X=[Co(NH3)5 Br] SO4, Y=[Co(NH3)5SO4]Br (C) X=[Co(NH3)5Br(SO4)], Y=[CoBr(SO4)(NH3)5] (D) X=[Co(Br)5NH3] SO4, Y=[CoBr(SO4)] NH3

Q. A coordination compound $X$ gives pale yellow colour with $A g N O_{3}$ solution while its isomer $Y$ gives white precipitate with $B a C l_{2}$ . Two compounds are isomers of $C o B r S O_{4} \cdot 5 N H_{3}$ . What could be the possible formula of $X$ and $Y$ ?

$X = [C o (N H_{3})_{5} S O_{4}] B r, Y = [C o (N H_{3})_{5} B r] S O_{4}$

$X = [C o (N H_{3})_{5} B r] S O_{4}, Y = [C o (N H_{3})_{5} S O_{4}] B r$

$X = [C o (N H_{3})_{5} B r (S O_{4})], Y = [C o B r (S O_{4}) (N H_{3})_{5}]$

$X = [C o (B r)_{5} N H_{3}] S O_{4}, Y = [C o B r (S O_{4})] N H_{3}$

$X [C o (N H_{3})_{5} S O_{4}] B r \to [C o (N H_{3})_{5} S O_{4}]^{+} + B r^{-}$
$A g N O_{3} + B r^{-} \to pale yellow A g B r + N O_{3}^{-}$
$Y [C o (N H_{3})_{5} B r] S O_{4} \to [C o (N H_{3})_{5} B r]^{2 +} + S O_{4}^{2 -}$
$B a C l_{2} + S O_{4}^{2 -} \to white ppt. B a S O_{4} + 2 C l^{-}$

Q. A coordination compound X gives pale yellow colour with AgNO3​ solution while its isomer Y gives white precipitate with BaCl2​. Two compounds are isomers of CoBrSO4​⋅5NH3​. What could be the possible formula of X and Y ?

X=[Co(NH3​)5​SO4​]Br,Y=[Co(NH3​)5​Br]SO4​

X=[Co(NH3​)5​Br]SO4​,Y=[Co(NH3​)5​SO4​]Br

X=[Co(NH3​)5​Br(SO4​)],Y=[CoBr(SO4​)(NH3​)5​]

X=[Co(Br)5​NH3​]SO4​,Y=[CoBr(SO4​)]NH3​
