Question

Trien is

• A. hexadentate, mono anionic
• B. tetradentate, neutral
• C. tetradentate, dianion
• D. monodentate, anion

Hint:

It has the chemical formula[CH₂NHCH₂CH₂NH₂]₂

Answer 1

The Correct Option is B

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.

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.

Answer 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.
