JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties
The correct order of electron affinity is
- A \(O> F > Cl\)
- B \(F > O > Cl\)
- C \(F > Cl > O\)
- D \(Cl> F > O\)
Answer & Solution
Correct Answer
(D) \(Cl> F > O\)
Step-by-step Solution
Detailed explanation
On moving from left to right across a period, the electron affinity becomes more negative. On moving from top to bottom in a group, the electron affinity becomes less negative. Chlorine has more negative electron affinity than fluorine, Because adding an electron to fluorine…
