Expert Answer
electron affinity increases across a period and decreases across a group.
exception- Cl> F (Because fluorine 2p orbital causes greater repulsion than adding electron to 3p orbital of chlorine ehich is larger in size)
Si>C ( Because Si has empty 3d orbital)
S>O (Because of smaller size of O, addition of extra electron causes more repulsion )
N<C (Because N has half filled 2p subshell)
So, Incorrect order is (2)
