For compound having the formula \(GaAlCl _4\), the correct option from the following is
- A \(Ga\) is more electronegative than \(Al\) and is present as a cationic part of the salt \(GaAlCl _4\)
- B Oxidation state of \(Ga\) in the salt \(GaAlC _4\) is \(+3\).
- C \(Cl\) forms bond with both \(Al\) and \(Ga\) in \(GaAlCl _4\)
- D \(Ga\) is coordinated with \(Cl\) in \(GaAlCl _4\)
Answer & Solution
Correct Answer
(A) \(Ga\) is more electronegative than \(Al\) and is present as a cationic part of the salt \(GaAlCl _4\)
Step-by-step Solution
Detailed explanation
Gallous tetrachloro aluminate \(Ga ^{+} AlCl _4^{-}\) \(2 Ga + Ga ^{+} GaCl _4^{-}+2 Al _2 Cl _6 \stackrel{190^{\circ}}{\longrightarrow} 4 Ga ^{+} AlCl _4^{-}\) Ga is cationic part of salt \(GaAlCl _4\).
