Question

write the oxidation state and covalency of Al in [Al F6]3-​

Answer 1

Answer:

The oxidation state of Al is +3. Covalency is number of atoms / ligands directly bonded to given atom. Here Al is bonded to 1 Cl atom and 5 water molecules , Hence covalency is 6. Covalency is 6

Explanation:

Answer 2

Answer:

Cl − is similarly pulled by Al 's + 3 oxidation state. Oxidation state of Al in given compound x+(-1)+5(0) = +2 x = +3 while covalency is 6. The oxidation state and covalency of [AlCl(H2O)5]2+ are +3, 6 respectively
