ALDEHYDES, KETONES AND CARBOXYLIC ACIDS

How will you convert ethanal to propanone?

Ethanal is a two-carbon aldehyde, and propanone is a three-carbon ketone. The increase in one Carbon number is possible using a Grignard reagent (Methyl Magnesium Bromide, CH₃MgBr) to form a new Carbon-Carbon bond.

Identify the Functional Isomers of C3H6O- Aldehydes, Ketones and Carboxylic Acids

Question- A and B are two functional isomers of compound C₃H₆O. On heating with NaOH and I₂, Isomer B forms a yellow precipitate of Iodoform whereas Isomer A does not form any precipitate. Write the formulae for A and B.

1) Functional Isomers are compounds that have same molecular formula but different functional groups.

Identify the Organic Compound with Molecular Formula C8H16O2- Aldehydes, Ketones and Carboxylic Acids

An Organic Compound 'A' molecular formula C₈H₁₆O₂ was hydrolyzed with dilute H₂SO₄ to give a carboxylic acid 'B' and an alcohol 'C.' Oxidation of 'C' with chromic acid also produced 'B.' On dehydration 'C' gives 1-but-ene. Write the equations for the reaction involved.

1) The first step is find out the Degree of Unsaturation (the number of double bonds or the presence of a ring) in the compound.

The formula is,
