Explanation

The iodoform test is a chemical reaction used to identify the presence of a methyl ketone group (CH3-CO-) in a compound.

When a methyl ketone reacts with iodine and sodium hydroxide, it produces a yellow precipitate of iodoform.

This makes the iodoform test a reliable way to detect methyl ketones.

Explanation

The functional group -COOH is the carboxyl group, which is a characteristic functional group of carboxylic acids.

Carboxylic acids are a class of organic compounds that contain this group, examples include:

• Formic acid (HCOOH)
• Acetic acid (CH3COOH)
• Citric acid (C6H8O7)

Explanation

• Hydrocarbon compounds are typically derived from fossil fuels and consist of hydrogen and carbon atoms.
• Examples include fuels like gasoline, natural gas, and propane, as well as waxes like candle wax and paraffin wax.
