Let be the denticity of ethylenediamine (en) and be the denticity of diethylenetriamine (dien). What — Coordination Compounds Chemistry Question

💡 Solution & Explanation

Ethylenediamine (en) has two $NH_2$ groups and coordinates through both, so its denticity $x = 2$. Diethylenetriamine (dien) has three nitrogen donor atoms, so its denticity $y = 3$. The required value is $(2 \times 3) + (2 + 3) = 6 + 5 = 11$.
