Iodoform Reaction Quiz

What is the chemical formula for iodoform?

• NaCl

• CO2

• H2O

• CHI3

Explain the mechanism of the iodoform reaction.

• The iodoform reaction is a chemical reaction in which a methyl ketone is oxidized to form a carboxylic acid and a molecule of iodoform (CHI3) in the presence of iodine and a base.

• The iodoform reaction is a chemical reaction in which a methyl ketone is reduced to form a carboxylic acid and a molecule of iodoform

• The iodoform reaction is a chemical reaction in which a methyl ketone is hydrolyzed to form a carboxylic acid and a molecule of iodoform

• The iodoform reaction is a chemical reaction in which a methyl ketone is dehydrated to form a carboxylic acid and a molecule of iodoform

What type of compounds undergo the iodoform reaction?

• Methyl ketones and alcohols with the CH3CO- group undergo the iodoform reaction.

• Sodium chloride and sulfuric acid

• Ethanol and water

• Propanol and sodium hydroxide

What is the role of hydroxide ions in the iodoform reaction?

• Hydroxide ions have no role in the iodoform reaction

• Hydroxide ions act as an acid in the iodoform reaction

• Hydroxide ions inhibit the iodoform reaction

• Hydroxide ions act as a base in the iodoform reaction, deprotonating the methyl ketone to form the iodoform precipitate.

How is the iodoform test used to identify the presence of certain functional groups?

• The iodoform test is used to identify the presence of carboxylic acids or compounds with the COO- group.

• The iodoform test is used to identify the presence of aldehydes or compounds with the COOH group.

• The iodoform test is used to identify the presence of alcohols or compounds with the OH group.

• The iodoform test is used to identify the presence of methyl ketones or compounds with the CH3CO- group. When a compound containing this group is treated with iodine and a base, it forms a yellow precipitate of iodoform, which confirms the presence of the functional group.
