Germinal dihalides on hydrolysis give

Options

A. Ketone only
B. Aldehydes
C. Acetone only
D. Ketones and aldehyde

Answer

To answer the question "Germinal dihalides on hydrolysis give," we can follow these steps:

### Step 1: Understand Geminal Dihalides
Geminal dihalides are organic compounds where two halogen atoms are attached to the same carbon atom. For example, in a compound like RCHCl2, the two chlorine atoms (Cl) are bonded to the same carbon (C).

### Step 2: Define Hydrolysis
Hydrolysis is a chemical reaction involving the addition of water (H2O) to a compound. In the case of geminal dihalides, hydrolysis will replace the halogen atoms with hydroxyl groups (OH).

### Step 3: Hydrolysis Reaction of Geminal Dihalides
When a geminal dihalide undergoes hydrolysis, the halogen atoms are replaced by hydroxyl groups. For example, if we take RCHCl2 and react it with water, the reaction can be represented as follows:
- RCHCl2 + H2O → RCHO + 2 HCl

In this reaction, the two chlorine atoms are replaced by one hydroxyl group (OH), and the other hydrogen atom (H) comes from the water molecule, resulting in the formation of an aldehyde (RCHO) and hydrochloric acid (HCl).

### Step 4: Consider Another Example
For another geminal dihalide, such as R2CCl2, the hydrolysis reaction would be:
- R2CCl2 + H2O → R2C=O + 2 HCl

Here, the product is a ketone (R2C=O) after the removal of the two chlorine atoms and the addition of water.

### Step 5: Conclusion
Thus, the hydrolysis of geminal dihalides results in the formation of either aldehydes or ketones, depending on the structure of the original compound.

### Final Answer
**Germinal dihalides on hydrolysis give aldehydes or ketones.**
