Neutral Anions include which of the following lists?

Neutral Anions include which of the following lists?

• A. F-, OH-, NO2-, CN-, SCN-, N3-
• B. Cl2-, Br2-, I2-, O2-, N2-, CO2
• C. Cl-, Br-, I-, NO3-, ClO4-, ClO3-
• D. HCO3-, SO4^2-, HSO4-, PO4^3-

Answer: (C)

Anions are negatively charged species, and when we talk about a single negative charge, we’re looking for monoanions with a -1 charge. The list that fits this idea includes halide ions like chloride, bromide, and iodide, plus common singly charged oxyanions such as nitrate, chlorate, and perchlorate. All of these have a -1 overall charge, which is the hallmark of a monoanion. The other options mix in items that aren’t typical singly charged species or involve ions with charges other than -1 (for example, ions with -2 or -3). That’s why the set of -1 charged ions best represents “neutral anions” in this context.
