Give two reactions in which aliphatic aldehydes differ from aromatic aldehdyes?

Explanation

To answer the question about how aliphatic aldehydes differ from aromatic aldehydes in two specific reactions, we can consider the following:

### Step-by-Step Solution:

1. **Tollens' Test:**
- **Aliphatic Aldehyde Reaction:** When an aliphatic aldehyde, such as acetaldehyde (CH₃CHO), is treated with Tollens' reagent (ammoniacal silver nitrate), it reduces the silver ions (Ag⁺) to metallic silver, resulting in a silver mirror on the test tube.
- **Aromatic Aldehyde Reaction:** In contrast, when an aromatic aldehyde like benzaldehyde (C₆H₅CHO) is treated with Tollens' reagent, it also gives a positive result, as both types of aldehydes can reduce silver ions.
