Give the IUPAC name of the only aldehyde which undergoes iodoform test.

Explanation

To determine the IUPAC name of the only aldehyde that undergoes the iodoform test, we can follow these steps:

### Step 1: Understand the Iodoform Test
The iodoform test is a chemical reaction that identifies the presence of methyl ketones or aldehydes that can be oxidized to methyl ketones. The test involves the reaction of the compound with iodine (I2) in the presence of a base such as sodium hydroxide (NaOH) or potassium hydroxide (KOH).

**Hint:** The iodoform test is specific for compounds that have a methyl group adjacent to a carbonyl group.

### Step 2: Identify Aldehydes That Can Undergo the Iodoform Test
