Question

which of the following is the correct name for bacl₂?
a. monobarium dichloride
b. barium chlorine
c. barium dichloride
d. barium chloride

Explanation:

When naming ionic compounds like $BaCl_2$, the metal (barium, $Ba$) is named first, followed by the non - metal (chlorine, $Cl$) with its ending changed to -ide. Prefixes are not used for ionic compounds with main - group metals like barium. So it is named barium chloride.

Answer:

D. Barium chloride
