Question

what is the correct name for the bro₄¹⁻ ion?
○ perbromate
○ bromite
○ bromate
○ hypobromite
○ none of the above

Explanation:

To name oxyanions of bromine, we follow the pattern: hypobromite ($\text{BrO}^-$), bromite ($\text{BrO}_2^-$), bromate ($\text{BrO}_3^-$), and perbromate ($\text{BrO}_4^-$). The ion given is $\text{BrO}_4^{1 - }$, so it corresponds to perbromate.

Answer:

A. perbromate
