CuSO4.5H2O me only 4 water molecules are attached to copper atom...(acording to jee 2009) my quest. is why not all 5 water molecules since coordination number of Cu2+ is 4 and 6 both...then why not 6

In CuSO4.5H2O, four water molecules are coordinated to Cu+2, while one is hydrogen bonded with SO42-.

Copper sulfate pentahydrate contains copper(II) in a geometry best described as distorted octahedral. The copper(II) is bound to four water molecules in a square-planar geometry and two oxygen atoms from two sulfate ions (one H2O is H-Bonded here).

This salt dissolves in water to produce the pale-blue [Cu(H2O)6]2+ ion, in which two of the water molecules are less tightly held and have longer bond distances.

according through werners theory one of thye five molecules of H2omolecules will attach to the  So4 molecules in the form of hydrozen bonding. it will act as both primary and secondary molecule so co-ordination number will be 4Smile

if you like it please approve
