Trien is
Show Hint
It has the chemical formula[CH2NHCH2CH2NH2]2
- hexadentate, mono anionic
- tetradentate, neutral
- tetradentate, dianion
- monodentate, anion
The Correct Option is B
Approach Solution - 1
The correct answer is Option B) tetradentate, neutral
It has the chemical formula[CH2NHCH2CH2NH2]2
It will look like C6H18N4
- It has four nitrogen atoms with lone pairs in it.
- It is characterized as a tetra-dentate ligand because these four nitrogen atoms are connected to the central atom by four passageways, allowing it to give electron pairs.
- Trien is neutral since it has no overall charge.

Approach Solution -2
The correct answer is Option B) tetradentate, neutral
Real-Life Applications
- A specific copper(II) chelator, triethylenetetramine (TETA), helps to increase the excretion of copper through the urine. It has been demonstrated to lessen excessive body copper accumulation and improve Wilson's disease symptoms. It also helps in treating in cancer, heart disease, and Alzheimer's disease.
- TETA is primarily employed in the production of epoxy curing agents, lubricating oil additives, and fuel oil additives.
- It is also employed in the creation of additives for asphalt. It also helps in crop growth.

Approach Solution -3
The correct answer is Option B) tetradentate, neutral
Trientine, commonly known as triethylenetetramine (TETA), is a strong and specific copper (II)-selective chelator.
- It is a structural analog of the spermidine and spermine linear polyamine compounds.
- In coordination chemistry, TETA is known as trien and is a tetradentate ligand.
Ligands
Atoms or groups that are directly joined to the core atom are referred to as ligands.
- Lewis bases known as ligands provide an electron pair to the metal atom and join with it to create coordinate bonds.
- H2O, CO, NO2, and more examples come to mind.
- A ligand might be positively, negatively, or neutrally charged.

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
