The most powerful oxidizing agent is Cl2.

Reason: an oxidizing agent is the species that is reduced, so you pick the half-reaction with the most positive standard reduction potential. Cl2 + 2e− → 2Cl− has the highest E° (~+1.36 V), > Br2 (~+1.07 V) > Sn2+ (negative E° for Sn2+ → Sn) > Cr3+ (negative/less positive), so Cl2 is strongest.
