Which is the paramagnetic oxide of chlorine ?
Correct answer: C. ClO2
- A. Cl2O7
- B. Cl2O6
- C. ClO2
- D. all
Explanation
ClO2 has an odd number of valence electrons, so one electron remains unpaired, making it paramagnetic. Cl2O7 has all electrons paired, and Cl2O6 is not the standard answer for this property in this comparison. Students may choose all because they assume every chlorine oxide contains unpaired electrons.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
