# Which of the following orders of electron affinities of halogen is correct?

$\begin{array}{1 1}F < Cl < Br\\F > Cl > Br\\F > Cl < Br\\F < Cl > Br\end{array}$

Answer : F < Cl > Br
Because of small size (electrons held in small volume),the electron affinity of F is smaller than Cl,which,in turn,has higher electron affinity than Br.
