In a cyclotrimetaphosphoric acid molecule, how many single and double bonds are present? 

(i) 3 double bonds; 9 single bonds 

(ii) 6 double bonds; 6 single bonds 

(iii) 3 double bonds; 12 single bonds 

(iv) Zero double bonds; 12 single bonds

This is a multiple choice answer as classified in NCERT Exemplar

Correct option is (iii)

H₃PO₂,  H₃PO₄,  H₃PO₄, and other oxoacids are formed by phosphorus. P is tetrahedrally surrounded by other atoms in phosphorus oxoacids. At least one P-H bond and an O-H bond are known to form in all of them.
