MnO2(s) + 4HCl(aq) → Cl2(g) + MnCl2(aq) + 2H2O(l)
is the required chemcial eqn. forthe preparation of Cl2 from MnO2.
d-block elements startiing from atomic number 21 to 30 mainly form Coordination compounds due to d orbitals present whicch participate into the bonding of central atoms from other ligands.
