Question

Use the IUPAC nomenclature rules to predict the chemical name for baking soda, NaHCO3?
A) Sodium bicarbonate
B) Sodium carbonic acid
C) Sodium hydrogen carbonate
D) Sodium hydrogen monocarbon trioxide

Answer 1

Answer:

C. Sodium hydrogen carbonate

Explanation:

IUPAC : International Union of Pure and Applied Chemistry.

According to IUPAC rules:

Baking soda is a salt formed by a cation(Positive charge) and an anion(anion).

$NaHCO_{3}$ : Is made from cation $Na^{+}$ and one anion

$HCO_{3}^{-}$

IUPAC naming starts from the cation name .(Here the cation name is : Sodium .) The cation is named same as the name of element.

Anion is named after the cation .Here $HCO_{3}^{-}$ is named as Hydrogen carbonate.(anion name ends with -ate ,-ite -ide etc).

So, name of the compound is Sodium hydrogen carbonate

Note: d.Sodium hydrogen monocarbon trioxide, can't be correct answer, because it show the existence of anions of oxygen($O^{-2}$)and not $HCO_{3}^{-}$)
