Question
- Why does tendency to show catenation decreases down the group?
- Why is $\mathrm{N}_2 \mathrm{O}$, more acidic than $\mathrm{N}_2 \mathrm{O}_3$ ?
✓
Answer
- It is because bond dissociation enthalpy decreases due to increase in bond length with the increase in atomic size of element.
- Higher the oxidation state, more will be acidic character, that is why $\mathrm{N}^2 \mathrm{O}^5$ is more acidic than $\mathrm{N}_2 \mathrm{O}_3$.
