Question
Identify the incorrect statement about othoboric acidSelect an answerAIt has a layer structure in which planer BO3 units are joined by hydrogen bondsBH3BO3 is a weak monobsic Lewis acidCOn heating orthoboric acid it forms metaboric acid and on further heating to red hot, forms boric oxide anhydrideDIt is obtained by reacting borax with HCl using phenolphthalein as an indicator
Solution
The incorrect statement is B. H3BO3 is a weak monobasic Lewis acid.
Orthoboric acid (H3BO3) is a weak monobasic Lewis acid, but it's not represented as H3BO3. The correct representation is B(OH)3. This is because in its structure, boron is surrounded by three hydroxyl groups.
