Question

Trien is:
A.)Hexa dentate, Mono anionic.
B.)Tetra dentate ,neutral.
C.)Tetra dentate, dianion.
D.)Mono dentate, anion.

Answer 1

Hint:The ions or central molecules that are attached with central atoms to donate electron pairs. Trien is also a ligand and it is called or famously known as Triethylenetetramine all over the globe. It is also called trientine.

Complete step by step answer:
-It is an organic compound. It has the chemical formula \[{[C{H_2}NHC{H_2}C{H_2}N{H_2}]_2}\] .
-It appears colorless but many times it appears yellowish because of impurities.
-It is present in polar solvents.
-As we can see in the above structure that it contains four nitrogen atoms containing lone pairs. These four nitrogen atoms are linked with the central atom in a coordination compound so it donates electron pairs via four passages, that’s why it is known as tetra-dentate ligand. Trien has no overall charge on it, so it is neutral in nature.
-Its chemical formula is ${C_6}{H_{18}}{N_4}$ .
-Its molar mass is $146.238g/mol$.
-Its density is $982mg/ml$ .
So our answer is option-B.
