I have worked to know several UPAC names of compounds but I found it hard to calculate and know the UPAC names of the following

. The book has given me the name but how to calculate to know(especially the one with no fixed state) has become the problem.

Fe(OH)2.

The book says Iron(II) hydroxide.

But how to calculate by using the oxidation number has become the problem.

I know only one thing - that is that I know nothing

My wife says: Learn that OH is minus one => (OH)2 is -2 => FE is +2
