which of these is a polyatomic ion??

Explanation:

Question 5

Organic compounds are defined as those containing carbon - hydrogen bonds (and usually other elements like O, N, etc.). Inorganic compounds, by contrast, typically lack carbon (with some exceptions like carbonates, but generally, they don't have carbon as a key part of their structure in the way organic compounds do). So the compound that typically does not contain carbon is inorganic.

A polyatomic ion is an ion composed of two or more atoms covalently bonded together and carrying a net charge. $Zn^{2 + }$ is a monoatomic cation (one zinc atom). $Br^{1 - }$ is a monoatomic anion (one bromine atom). $OH^{1 - }$ is composed of one oxygen and one hydrogen atom, so it is a polyatomic ion. $N^{3 - }$ is a monoatomic anion (one nitrogen atom).

Answer:

B. Inorganic
