Chlorine atom withdraws electrons by I effect as it is more electronegative than carbon atom. It donates electrons by resonance effect by donating electron pair by electromeric effect.
oxidation is a process in oxygen is added to a substace . e.g.
1 : - 4na + o₂ > > > > 2na₂o
2: - 2h₂ + o₂> > > > 2h₂o
reduction is the process in oxygen is removed from a substance . eg.
1 : - cuo+h₂> > > > cu+h₂o
2: - 2pbo+c> > > > > pb+co₂
redox is a combination if oxidation and reactions involves transfer of electrons between two species. e.g.
1: - 2fe³⁺ + sn2+===> > > 2fe²⁺ + sn⁴⁺
2: - fe + cu²⁺ > > > fe²⁺ + cu
