Explain formation of electrovalent compound is a redox reaction.
Chemical Bonding
Answer
In the formation of electrovalent compounds, the transfer of electrons is involved. The electropositive atom loses electrons and undergoes oxidation while the electronegative atom gains electrons and undergoes reduction. Hence, formation of electrovalent compound is a redox reaction.
