**Question:**

Which statement is true regarding \([Fe(en)_3]^{2+}\)?

**Options:**

- The coordination complex has an optical isomer.
- The coordination complex has no isomers of any type.
- The coordination complex has a coordination isomer.
- The coordination complex has a geometric isomer.
- The coordination complex has a linkage isomer.

This question focuses on the properties of the coordination complex \([Fe(en)_3]^{2+}\), specifically its isomeric characteristics. The options explore different types of isomerism that may be present in coordination compounds, such as optical, geometric, linkage, and coordination isomerism.

**Question:** Which of these molecules is *chiral*? Select all that apply.

**Diagram Explanation:**

1. **Molecule I:** The structure consists of a central carbon atom (C) bonded to four different atoms/groups: Fluorine (F), Bromine (Br), Chlorine (Cl), and Hydrogen (H).

2. **Molecule II:** This structure has a central atom denoted as M, bonded to four groups: two identical groups labeled as L, and two identical groups labeled as X.

3. **Molecule III:** Here, the central atom M is bonded to three different groups: two groups labeled as A, and one group labeled as C, and a group labeled as B.

**Selection:**

- [x] Molecule I
- [x] Molecule III
- [ ] Molecule II

Molecules I and III are selected as chiral. Chiral molecules have a non-superimposable mirror image due to the presence of four different groups bonded to a central atom. Molecule II is not chiral because it has identical groups, leading to a symmetrical structure.
