AP EAMCET · Chemistry · Classification of Elements and Periodicity in Properties
Arrange N, S, O and F in order of decreasing electron gain enthalpy.
- A \(\mathrm{F}>\mathrm{S}>\mathrm{O}>\mathrm{N}\)
- B \(\mathrm{N}>\mathrm{O}>\mathrm{S}>\mathrm{F}\)
- C \(\mathrm{O}>\mathrm{S}>\mathrm{F}>\mathrm{N}\)
- D \(\mathrm{S}>\mathrm{O}>\mathrm{N}>\mathrm{F}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{F}>\mathrm{S}>\mathrm{O}>\mathrm{N}\)
Step-by-step Solution
Detailed explanation
Electron gain enthalpy increases with decrease in atomic size. On moving from left to right in the periodic table, the atomic size decreases and electron gain enthalpy increase for fluorine. In case of oxygen, due to its small size and compact nature, the incoming electron is…
