Calculate the denticity of the ligand (commonly known as tren). — Coordination Compounds Chemistry Question

💡 Solution & Explanation

The molecule $N(CH_2CH_2NH_2)_3$ consists of a central tertiary nitrogen atom and three primary amine ($NH_2$) groups at the ends of the branches. Each nitrogen atom has one lone pair available for donation. Thus, there are $1 + 3 = 4$ donor atoms, making it a tetradentate ligand.
