Name the aldehyde which does not give Fehling solution test.

Explanation

To solve the question of naming the aldehyde that does not give a Fehling's solution test, we can follow these steps:

### Step 1: Understand the Fehling's Test
Fehling's test is a qualitative test used to differentiate between aldehydes and ketones. It involves the reaction of an aldehyde with Fehling's solution, which contains copper(II) ions. Aldehydes typically reduce Cu²⁺ ions to Cu⁺ ions, resulting in a color change (from blue to red precipitate).

### Step 2: Identify Aldehydes
Aldehydes are organic compounds characterized by the presence of a carbonyl group (C=O) at the end of a carbon chain. They can be classified as either aliphatic or aromatic.
