Propylidene chloride when heated with zinc gives -

Options

A. Ethene
B. Propene
C. 1-Butene
D. 3-Hexene

Answer

To solve the question of what product is formed when propylidene chloride is heated with zinc, we can follow these steps:

### Step 1: Identify the structure of propylidene chloride
Propylidene chloride is also known as 1,1-dichloropropene. The structure can be represented as follows:
- The central carbon (C) has two chlorine (Cl) atoms attached to it, while the other two carbons are attached to the central carbon and are part of the propyl group.

### Step 2: Understand the reaction type
When propylidene chloride is heated with zinc, it undergoes an elimination reaction. In this case, zinc acts as a reducing agent and facilitates the removal of the chlorine atoms.

### Step 3: Elimination of chlorine
In the elimination reaction, both chlorine atoms (Cl) attached to the central carbon are removed. This results in the formation of a double bond between the two adjacent carbon atoms.

### Step 4: Determine the product
After the elimination of the two chlorine atoms, the structure of propylidene chloride changes to:
- CH2=CH-CH3, which is the structure of propene.

### Conclusion
Thus, when propylidene chloride is heated with zinc, the product formed is propene.

### Final Answer
**Propene** is the product formed when propylidene chloride is heated with zinc.
