What is the correct name for the compound with the formula NH4Cl?
A
Ammonium hypochlorite
B
Ammonium chlorate
C
Ammonium chloride
D
Ammonium chlorite
Verified step by step guidance1
Identify the ions present in the compound NH4Cl. NH4 is the ammonium ion, and Cl is the chloride ion.
Recall that the ammonium ion (NH4\textsuperscript{+}) is a polyatomic cation, and chloride (Cl\textsuperscript{-}) is a monatomic anion.
Combine the names of the cation and anion to name the compound. The cation name comes first, followed by the anion name.
Since the anion is chloride (not hypochlorite, chlorate, or chlorite, which are different oxyanions of chlorine), the correct name is ammonium chloride.
Verify that the formula matches the name: NH4Cl corresponds to ammonium chloride, confirming the correct naming.
