When methyl bromide is heated with Zn it gives:

Options

A. `CH_(4)`
B. `C_(2)H_(6)`
C. `C_(2)H_(4)`
D. `CH_(3)`OH

Answer

To solve the question "When methyl bromide is heated with Zn it gives:", we will follow these steps:

### Step 1: Identify the Reactants
The reactant in this case is methyl bromide (CH₃Br), which is an alkyl halide.

**Hint:** Remember that alkyl halides are compounds where a halogen atom is bonded to an alkyl group.

### Step 2: Understand the Reaction Conditions
The reaction involves heating methyl bromide with zinc (Zn). This indicates that we are likely dealing with a reduction reaction.

**Hint:** Heating often facilitates reactions by providing the necessary energy for the reaction to occur.

### Step 3: Recognize the Type of Reaction
The reaction between an alkyl halide and zinc under heating conditions is known as the Franklin reaction. This reaction typically involves two equivalents of alkyl halide reacting with zinc to form an alkane and a zinc halide.

**Hint:** Familiarize yourself with common reactions involving alkyl halides, as they often follow predictable patterns.

### Step 4: Determine the Product
In the case of methyl bromide, which has one carbon atom (C), when it reacts with zinc, it will produce an alkane with two carbon atoms (C₂). Therefore, the product formed will be ethane (C₂H₆).

**Hint:** The number of carbon atoms in the alkane product is typically one more than the number of carbon atoms in the alkyl halide reactant.

### Step 5: Identify the Byproduct
Along with ethane, zinc bromide (ZnBr₂) will be formed as a byproduct of the reaction.

**Hint:** Always consider the byproducts of a reaction, as they can provide additional context about the reaction process.

### Conclusion
Thus, when methyl bromide is heated with zinc, the major product formed is ethane (C₂H₆), and the byproduct is zinc bromide (ZnBr₂).

**Final Answer:** Ethane (C₂H₆) is the product obtained when methyl bromide is heated with zinc.
