Question
The number of hydrogen atom(s) attached to phosphorus atom in hypophosphorous acid is
Solution
Hypophosphorous acid has the chemical formula H3PO2.
Step 1: Identify the elements in the formula. Here, we have Hydrogen (H), Phosphorus (P), and Oxygen (O).
Step 2: Look at the subscript numbers following each element. These numbers tell you how many atoms of each element are present in a molecule of the compound.
Step 3: In H3PO2, the subscript 3 after H indicates that there are 3 hydrogen atoms attached to the phosphorus atom in a molecule of hypophosphorous acid.
So, the number of hydrogen atoms attached to the phosphorus atom in hypophosphorous acid is 3.
