When chloroform is heated with aqueous NaOH, it gives :

Options

A. Formic acid
B. Sodium formate
C. Acetic acid
D. Sodium acetate

Explanation

To solve the question of what product is formed when chloroform is heated with aqueous NaOH, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are chloroform (CHCl3) and aqueous sodium hydroxide (NaOH).

**Hint:** Always start by identifying the substances involved in the reaction.

### Step 2: Understand the Reaction Conditions
Chloroform is heated with aqueous NaOH. The heating indicates that a reaction will take place, likely involving the breakdown of chloroform and the formation of new products.

**Hint:** Consider how heat can influence chemical reactions, often leading to decomposition or substitution reactions.

### Step 3: Write the Reaction
When chloroform (CHCl3) is treated with aqueous NaOH, it undergoes a reaction where three moles of NaOH react with one mole of chloroform. The reaction can be represented as follows:

\[ \text{CHCl}_3 + 3 \text{NaOH} \rightarrow \text{HCOONa} + 3 \text{NaCl} + 2 \text{H}_2\text{O} \]

**Hint:** Pay attention to the stoichiometry of the reaction. How many moles of each reactant are involved?

### Step 4: Identify the Intermediate Products
During the reaction, chloroform is first converted into an unstable intermediate (which is not isolated), and then it further reacts to form formic acid (HCOOH). The formic acid then reacts with NaOH to form sodium formate (HCOONa).

**Hint:** Consider the possibility of intermediate products and how they can lead to the final product.

### Step 5: Determine the Final Product
The final product of the reaction is sodium formate (HCOONa), which is formed after the reaction of formic acid with sodium hydroxide.

**Hint:** The final product is often a salt when an acid reacts with a base.

### Conclusion
When chloroform is heated with aqueous NaOH, the product formed is sodium formate (HCOONa).

**Final Answer:** Sodium formate (Option 2).
