Question

What is the correct name for $Fe(OH{)}_3$?

• A. Iron(III) hydroxide
• B. Iron hydroxide (III)
• C. (III)iron hydroxide
• D. Iron (III) hydroxate
• E. Iron hydroxate (III)

Answer 1

The correct option is A Iron(III) hydroxide

$Fe(OH{)}_3$ has the correct name "Iron(III) hydroxide". As iron is the name of "Fe" element and being negative part $OH$ is written as "hydroxide" and as the charge of $Fe$ is $+3$, hence, in the bracket, III is written in roman.
