The positive iodoform test is a chemical test used to identify the presence of a methyl ketone or a compound containing a methyl ketone functional group. In this test, a yellow precipitate of iodoform (CHI3) is formed when a compound reacts with iodine (I2) in the presence of a mild base, such as sodium hydroxide (NaOH).
In the given options, the compound that gives a positive iodoform test is 2-pentanone (option C). Let's understand why this is the correct answer.
Explanation:
1. 1-pentanol (option A): This compound is an alcohol and does not contain a methyl ketone functional group. Therefore, it will not give a positive iodoform test.
2. 3-pentanone (option B): This compound is a methyl ketone and contains a methyl ketone functional group. Hence, it has the potential to give a positive iodoform test.
3. 2-pentanone (option C): This compound is also a methyl ketone and contains a methyl ketone functional group (the ketone group is attached to the second carbon atom). Therefore, it will give a positive iodoform test.
4. Pentanal (option D): This compound is an aldehyde and does not contain a methyl ketone functional group. Thus, it will not give a positive iodoform test.
To summarize, the compound that gives a positive iodoform test is 2-pentanone (option C) because it contains a methyl ketone functional group. This functional group reacts with iodine and a mild base to form iodoform, which is observed as a yellow precipitate.
