Which among the following is paramagnetic?
Which among the following is paramagnetic?
Show Hint
A species with one or more unpaired electrons is paramagnetic.
- Cl2O
- ClO2
- Cl2O7
- Cl2O6
The Correct Option is B
Solution and Explanation
A species with one or more unpaired electrons is paramagnetic.
No. of valence electrons in Cl2O = 7 x 2 + 6 = 20 (even)
No. of valence electrons in ClO2 = 7 + 6 x 2 = 19 (odd)
No. of valence electrons in Cl2O7 = 7 x 2 + 6 x 7 = 56 (even)
No. of valence electrons in Cl2O6 = 7 x 2 + 6 x 6 = 50 (even)
Thus, ClO2 is expected to be paramagnetic.

- An electron (mass \(9 \times 10^{-31}\) kg and charge \(1.6 \times 10^{-19}\) C) moving with speed \(c/100\) (\(c\) = speed of light) is injected into a magnetic field of magnitude \(9 \times 10^{-4}\) T perpendicular to its direction of motion. We wish to apply a uniform electric field \( \vec{E} \) together with the magnetic field so that the electron does not deflect from its path. (speed of light \(c = 3 \times 10^8\) m/s):

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
