Electron affinity (in kJ textmo textl text-1 ) of F = 332.6, Cl = 348.5, Br = 324.7 and I = 295.5. Chlorine has highest electron affinity value, So, according to question the correct order will be Cl2>F2>Br2 .

Q. The electron affinity values (in kJ $m o l^{- 1}$ ) of three halogens X, Y, Z are respectively -349, -333 and -325. Then X, Y and Z respectively are

$F_{2}, C l_{2}$ and $B r_{2}$

$C l_{2}, F_{2}$ and $B r_{2}$

$C l_{2}, B r_{2}$ and $F_{2}$

$B r_{2}, C l_{2}$ and $F_{2}$

Electron affinity (in kJ $mo l^{-1}$ ) of F = 332.6, Cl = 348.5, Br = 324.7 and I = 295.5. Chlorine has highest electron affinity value, So, according to question the correct order will be $C l_{2} > F_{2} > B r_{2}$ .
