Dear Chandan
Electron affinity increases from left to right in a period and decreses from top to bottom in a group.
Si has 3p- orbitals which accommodate the extra electron with ease while adding extra electron to C leads repulsion due to small sie of 2 p – orbitals. Therefore Si has higher electron affinity than C.
