Which of the following oxy anion(s) contain(s) P—O bond order equal to 1.5 ? — p Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Aluminum chloride (AlCl3) is a salt of a strong acid (HCl) and a weak base (Al(OH)3). Step 2: In aqueous solution, it undergoes highly favorable hydrolysis: AlCl3 + 3H2O -> Al(OH)3 + 3HCl. Step 3: Therefore, the primary hydrolysis product is the gelatinous precipitate of aluminum hydroxide, Al(OH)3, which corresponds to option (b).
