Question

AgCl and NaCl are colourless NaBr and NaI are also colourless but AgBr and Agl are coloured. This is due to (A) Ag+ has half-filled d-orbital (B) Ag+ polarises Br- and I- (C) Ag+ depolarises Br- and I- (D) None is correct

AgCl, NaCl, NaBr, NaI less polarization, more ionic, colourless AgBr, AgI more polarization, less ionic, more covalent, coloured

Q. $A g Cl$ and $N a Cl$ are colourless $N a B r$ and $N a I$ are also colourless but $A g B r$ and $A g l$ are coloured. This is due to

$A g^{+}$ has half-filled $d$ -orbital

$A g^{+}$ polarises $B r^{-}$ and $I^{-}$

$A g^{+}$ depolarises $B r^{-}$ and $I^{-}$

None is correct

$A g Cl, N a Cl, N a B r, N a I$ less polarization, more ionic, colourless $A g B r, A g I$ more polarization, less ionic, more covalent, coloured

Q. AgCl and NaCl are colourless NaBr and NaI are also colourless but AgBr and Agl are coloured. This is due to

Ag+ has half-filled d-orbital

Ag+ polarises Br− and I−

Ag+ depolarises Br− and I−
