In complex nomenclature, "ammine" refers to ammonia as a ligand while "amino" refers to -NH₂ group.

Solution

Chemistry ma’am · 3 steps

Watch the double m: ammine with two m's is the ammonia ligand, amino is the organic –NH₂ group.

1. Ammine. Neutral NH₃ bonded to a metal through its lone pair is named ammine, spelled with a double m. For example, [Co(NH₃)₆]Cl₃ is hexaamminecobalt(III) chloride.
2. Amino. Amino is the prefix for the -NH₂ group attached to carbon in organic compounds, as in 2-aminoethanoic acid (glycine). It has a single m and is a substituent name, not the name of the ammonia ligand.

   Species	Name	Where you meet it
   NH₃, neutral	ammine	ligand in a complex
   NH₂⁻, anion	amido	anionic ligand in a complex
   -NH₂ on carbon	amino	substituent in organic compounds

3. So. Ammine means the ammonia ligand and amino means the -NH₂ group, so the statement is true.

The idea to keep. For nitrogen names, check both the species and its charge. Neutral NH₃ ligand is ammine (double m), the anion NH₂⁻ is amido, and the organic -NH₂ group is amino.
