. Draw the structure of and identify the number

Best Answer

Solution:

It is the anhydride of orthophosphoric acid,  (phosphorus trioxide) therefore also known as phosphorous oxide or phosphorous anhydride. P₄O₆

It is a solid soft white color. It is an anhydride of an acid so it behaves as  an acidic and will hydrolyze in water to generate phosphorous acid. Phosphorus trioxide is a dimer with the formula . P₄O₆

Structure of can be shown as: P₄O₆

Number of single P-O bonds are 12 as shown in the figure.
