Out of given reaction which show change in hybridization of central atom__________.

Which of the following primary and secondary valencies are not correctly marked against the compound?

The magnitude of CFSE (Crystal Field Splitting Energy, $$\Delta_0$$) can be related to the configuration of d - orbitals in a coordination entity as?

Aqueous solution of nickel sulphate on treating with pyridine and then adding a solution of sodium nitrate gives dark blue crystals of:

The terminal and bridged $$CO$$ ligands in the compound $$[Co_2(CO)_8]$$ are respectively:

The two isomers X and Y with the formula $$Cr(H_2O)_5ClBr_2$$ were taken for experiment on depression in freezing point. It was found that one mole of X gave depression corresponding to $$2$$ moles of particles and one mole of Y gave depression due to $$3$$ moles of particles. The structural formulae of X and Y respectively are:
