A compound that gives a positive iodofrm test is `:`

Options

A. 1-pentanol
B. 3-pentanone
C. 2-pentanone
D. pentanal

Explanation

To determine which compound gives a positive iodoform test, we need to follow these steps:

### Step 1: Understand the Iodoform Test
The iodoform test is used to identify compounds that contain a methyl ketone (a ketone with the structure R-CO-CH3) or a secondary alcohol that can be oxidized to a methyl ketone. The test is performed using sodium hydroxide (NaOH) and iodine (I2).

**Hint:** Remember that the presence of a methyl group (CH3) adjacent to a carbonyl group (C=O) is crucial for a positive iodoform test.

### Step 2: Identify the Functional Group
