MCQ
Which of the following is a cyclic phosphate
- A${H_5}{P_3}{O_{10}}$
- B${H_6}{P_4}{O_{13}}$
- ✓${H_5}{P_5}{O_{15}}$
- D${H_7}{P_5}{O_{16}}$
✓
Answer
Correct option: C.
${H_5}{P_5}{O_{15}}$
c
Cyclic phosphates have basic molecular formula as $\left( HP O _3\right)_{ n }$
Cyclic phosphates have basic molecular formula as $\left( HP O _3\right)_{ n }$
Therefore only $H _5 P _5 O _{15}=\left( HPO _3\right)_5$ satisfies this.
