Solution

The correct option is A $A l C l_{3}$
$A l + 3 N a O H ⟶ A l (O H)_{3} + 3 N a^{+}$
(white ppt.)

$A l (O H)_{3} + N a O H ⟶ N a^{+} [A l (O H)_{4}]^{-}$ (Compound B)
(soluble complex)

$A l (O H)_{3} + 3 H C l ⟶ A l C l_{3} + 3 H_{2} O$
(dil) (Compound C)

$2 A l (O H)_{3} S t r o n g - ----- \to h e a t i n g △ A l_{2} O_{3} + 3 H_{2} O$
$↓$
(used to extract metals)
Compound $D = A l_{2} O_{3}$

Compound $A = A l (O H)_{3}$

Compound $B = N a^{+} [A l (O H)_{4}]^{-}$

Compound $C = A l C l_{3}$

Compound $D = A l_{2} O_{3}$
