A synthesis (combination) reaction gives one product from two or more reactants. Here the reaction produces two products (KCl and I2), so it is not a synthesis reaction. It is a single‑replacement (halogen displacement) redox reaction:

Cl2 + 2 KI → 2 KCl + I2

(Cl2 is reduced to Cl− and I− is oxidized to I2.)
