WebSep 9, 2024 · 1 Answer. It is important to clearly separate the terms denticity, hapticity and bridging. An atom or a ligand is bridging is one single atom bonds to two different acceptors. A ligand (but never a single atom) can be multidentate or multihaptic if two atoms of that ligand can bond to the same acceptor. A ligand such as the amide anion cannot ... WebDec 6, 2024 · Re: denticity. Postby Riya Sawhney 1C » Mon Dec 06, 2024 12:46 am. Denticity refers to the number of bonds a single ligand can form with a central atom.For example, EDTA, shown below, is hexadentate, meaning it can form 6 bonds. Sigma bonds can rotate, and so parts of the molecule can rotate into the correct position.
