`[Fe(en)_(2)(H_(2)O)_(2)]^(2+) +en to " complex(X)"`. The correct statement about the complex (X) is

Options

A. it is low spin complex
B. it is diamagnetic
C. it shows geometrical isomerism
D. (1) and (2) both.

Answer

D

Explanation

`[Fe(en)_(2)(H_(2)O)_(2)]^(2) +en to [Fe(en)_(3)]^(2+)+2H_(2)O`
Complex is `[Fe(en)_(3)]^(2+). `'en' is a strong field ligand and thus it is inner orbital complex `(d^(2)sp^(3))` and diamagnetic .
It is `M(A A)_(3)` type which has only one form.
