Match the terms in Column-I with their description in Column-II:Column-I Column-II P N2O5 (i) N–N bond Q N2O (ii) N–O–N bond R N2O4 (iii) N=N / N≡N bond S NO2 (iv) N=O bond
| Column-I | Column-II | ||
| P | N2O5 | (i) | N–N bond |
| Q | N2O | (ii) | N–O–N bond |
| R | N2O4 | (iii) | N=N / N≡N bond |
| S | NO2 | (iv) | N=O bond |
Solution and Explanation
- P: N2O5 contains an N–O–N bond due to its molecular structure.
- Q: N2O has an N≡N or N=N bond as it is a linear molecule with nitrogen atoms bonded to each other.
- R: N2O4 contains an N–N bond due to its dimerized structure (dinitrogen tetroxide).
- S: NO2 has an N=O bond due to its resonance structure involving nitrogen and oxygen.
Correct Answer:
P – (ii), Q – (iii), R – (i), S – (iv)

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
