Do Esters Give Iodoform Test?

Carbonyl compounds (aldehydes and ketones having methyl group \[C{H_3}\] group at position) give the iodoform test. Ethyl acetoacetate

Ethyl acetoacetate
Acetoacetic ester synthesis is a chemical reaction where ethyl acetoacetate is alkylated at the α-carbon to both carbonyl groups and then converted into a ketone, or more specifically an α-substituted acetone. This is very similar to malonic ester synthesis.

\[C{H_3}COC{H_2}COOC{H_2}C{H_3}\] is a carboxylic acid derivative, more specifically an ester. Carboxylic acid derivatives do not give the iodoform test.

Which element does not give iodoform test?

- So, among the given options only option B will not give the positive iodoform test because there is no presence of the methyl group in the molecule. Therefore, option B is the correct answer. Note: As we know that iodine has antiseptic properties.

Which compounds can give iodoform test?

Compounds That Give Positive Iodoform Test
  • Acetaldehyde.
  • Methyl Ketones.
  • Ethanol.
  • Secondary Alcohols that contain Methyl Groups in Alpha Position.
