Ethylene diammine is ligand________?
Correct answer: B. Bi dentate
- A. mono dentate
- B. Bi dentate
- C. tri dentate
- D. Poly dentate
Explanation
Ethylenediamine, H2NCH2CH2NH2, has two nitrogen donor atoms, and each nitrogen can donate a lone pair to the same metal ion. It therefore binds through two sites and is a bidentate ligand. The likely wrong choice is monodentate, caused by counting the ligand molecule rather than its donor atoms.

About Shapes of Orbitals
Atomic orbitals are three-dimensional regions where an electron is most likely to be found, not fixed circular paths. The content covers the spherical s orbitals, dumbbell-shaped p orbitals, clover-shaped d orbitals, the orientations of orbitals, and how quantum numbers determine their shapes and energy levels.
