For the reaction of phenol with `CHCl_(3)` in presence of KOH, the electrophile is

Options

A. `overset(+)CHCl_(2)`
B. `:C"C"l_(2)`
C. `overset(cdot)CHCl_(2)`
D. `"C"Cl_(4)`

Explanation

To determine the electrophile in the reaction of phenol with CHCl₃ in the presence of KOH, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are phenol (C₆H₅OH) and chloroform (CHCl₃) in the presence of a strong base, KOH.

**Hint:** Look for the components involved in the reaction to understand their roles.

### Step 2: Understand the Role of KOH
KOH acts as a strong base that will deprotonate phenol, generating a phenoxide ion (C₆H₅O⁻). This ion is more nucleophilic than phenol itself.

**Hint:** Consider how strong bases interact with acidic protons to form more reactive species.

### Step 3: Analyze the Reaction of CHCl₃ with KOH
When CHCl₃ reacts with KOH, it undergoes a reaction that leads to the formation of dichlorocarbene (CCl₂). The KOH facilitates the removal of a hydrogen atom from CHCl₃, resulting in the generation of CCl₂.

**Hint:** Focus on how halogenated compounds can react with bases to form reactive intermediates.

### Step 4: Identify the Electrophile
In this reaction, the electrophile is the dichlorocarbene (CCl₂) that is generated. This species is highly reactive and can attack the nucleophilic phenoxide ion formed from phenol.

**Hint:** Recall that an electrophile is a species that accepts an electron pair, typically a positively charged or electron-deficient species.

### Step 5: Conclusion
Thus, the electrophile in the reaction of phenol with CHCl₃ in the presence of KOH is CCl₂.

**Final Answer:** The electrophile is CCl₂.
