Question

The number of carbon atoms in hydrogen carbonate radical is

• A. One
• B. Two
• C. Three
• D. Four

Answer 1

The correct option is A

One

Explanation for correct option:

Option A

Radical:

• A radical is defined as an atom or a group of atoms that carries a positive or negative charge and behaves as a single unit in chemical reactions.
• A radical is represented by writing its formula and putting charges equal to its valency on the right-hand top.

For example:

• The formula of hydrogen carbonate is ${{\mathrm{HCO}}_3}^{-}$, so the number of carbon atoms in hydrogen carbonate is one.

Therefore, Option A is correct.
