Answer 1

please mark me brainliest

Answer 2

Answer:

Concept:

The organic molecule ethylenediamine, sometimes known as en when a ligand, has the chemical formula C2H4(NH2)2. A basic amine is this white liquid with an ammonia-like smell. With over 500,000 tonnes produced in 1998, it is a frequently utilized building material in chemical synthesis.   The first members of the so-called polyethylene amines is ethylenediamine.

Given:

For the complex [Fe(en)2Cl2]Cl, (en = ethylenediamine),

(i) identify oxidation number

(ii) hybridization and shape

Answer:

• The following guidelines can be used to assign an oxidation number to a specific element or molecule.
• Any element that is free has an oxidation number of zero.
• The oxidation number for monoatomic ions always equals the ion's associated net charge.

(i).

$[F_{e} (en)2cl_{2} ]cl (or)x+0+2(-1)+(-1)=0\\x+(-3)=0(or)x=+3$

Iron's oxidation number, $x=+3$

Calculating an atom's steric number, which is equal to the sum of the number of lone pairs on the atoms plus the number of sigma bonds encircling the atom, is one method for determining the degree of hybridization. In this video, we concentrate on sp3 hybridized atoms, or atoms having a steric number of 4.

(ii) The complex consists of two monodentate and two bidentate ligands. As a result, the hybridization will be $d_{2} Sp_{3}$ and the shape will be octahedral, and the coordination number is 6.
