The compound of which P₄O₆ is the anhydride is ________.

Question

Quizplus · Accepted Answer

The anhydride of a carboxylic acid is formed by the removal of a water molecule from two acid molecules. In the given compound, P₄O₆, we can see that two carboxylic acid groups P₄OH and P₆OH are present. On removing a water molecule, we get the anhydride, which is represented as P₄O···O···₆. Since the anhydride is formed by joining the two carboxylic acid groups, the correct formula should be written in the order of P₄O-group-₆O. Among the given choices, the only option with this order of groups is C, which is H₃PO₃.
