**Question:**1. Which one of the following four schemes (A-D) represents a step in the *mechanism* of the reaction in the box?**Reaction in the Box:**\[ \text{(Isobutane)} \rightarrow \text{(Chlorination)} \rightarrow \text{(Chloro isobutane) + HCl} \] **Reagents:** \(\text{Cl}_2, \text{light (hv)}\)**Schemes:**- **A:** Shows the abstraction of a hydrogen atom from isobutane by a chlorine radical (\(\text{Cl}^\cdot\)) to form isobutyl radical and HCl.- **B:** Depicts a chlorine atom (\(\text{Cl}^\cdot\)) being added to a hydrogen, with an incorrect depiction of bond breaking and forming.- **C:** Illustrates a chlorine molecule (\(\text{Cl}_2\)) approaching isobutane without cleavage, which is not typical in radical chlorination.- **D:** Represents an abstraction of a hydrogen atom from isobutane by chlorine radical (\(\text{Cl}^\cdot\)), forming isobutyl radical and HCl.**Multiple Choice Options:**- ○ B- ○ D- ○ C- ○ AThe correct answer represents the radical chain initiation and propagation step involving the abstraction of a hydrogen by a chlorine radical, which is typical for radical halogenation reactions.**Graphs/Diagrams:**- **Scheme A:** Displays an arrow from the hydrogen on isobutane to a chlorine radical, indicating the generation of isobutyl radical and HCl.- **Scheme B:** Incorrectly shows a chlorine atom directly forming a new bond with hydrogen without any radical process.- **Scheme C:** Shows two chlorine atoms approaching the isobutane, not representing radical formation.- **Scheme D:** Similar to Scheme A with accurate radical abstraction depiction. **Answer: Choice D**
