Covalent Bond

Anhydrous A...

Question

Anhydrous $A l C l_{3}$ is covalent. from the data given below
Lattice Energy $= 5137 K J m o l^{- 1}$
$△ H h y d r a t i o n A l^{3 +} = - 4665 K J / m o l^{- 1}$
$△ H h y d r a t i o n C l^{-} = - 381 K J / m o l^{- 1}$

Solution

The correct option is D The solution will consists of $A I^{3 +}$ and $C I^{-}$
$A l C l_{3} (a n h y d r o u s) \to A l C l_{3} (a q)$

$Δ H$ of reaction= Energy rleased during hydration + Energy used during ionization
$\Rightarrow - 4665 - (3 \times 381) + 5137 = - 671$

Thus $A l C l_{3}$ would become ionic in aqueous solution as the formation of ions will take place because $Δ H_{h y d r a t i o n} > Δ H_{i o n i z a t i o n}$
