Question

How do we determine covalency of al in [AlCl(h20)5]2+ molecule???

Answer 1

oxidation state of Al= x
oxidation state of Cl= -1

so, x-1+6 x 0= +2
x=+3

Since H20 is attached to the Al atom, so its covalency is 6

Answer 2

oxidation state of Al= xoxidation state of Cl= -1so, x-1+6 x 0= +2x=+3Since H20 is attached to the Al atom, so its covalency is 6
