A) \[O<S<F<Cl\]
B) \[Cl<F<S<O\]
C) \[S<O<Cl<F\]
D) \[F<Cl<O<S\]
Correct Answer: B
Solution :
Halogens have very high electron affinity. It may be rated that the electron affinity of fluorine is unexpectedly low \[(<Cl)\]. This may perhaps be due to small size of F atom. The value of electron gain enthalpies for \[Cl,\,F,\,S\] and O are respectively 349, 333, 200 & 142 KJ / mol hence correct order is \[Cl>F>S>O\]You need to login to perform this action.
