Compound A reacts with 1 molar equivalent(s) of hydrogen upon catalytic hydrogenation. A undergoes reaction with ozone, followed by Zn treatment, to give:Propose a structure for A. The image depicts the structural formula of acetone (propanone). It consists of three carbon atoms, six hydrogen atoms, and one oxygen atom arranged as follows:- A central carbon atom is double-bonded to an oxygen atom, forming a carbonyl group (C=O).- This carbon is also singly bonded to two CH₃ groups (methyl groups), one on each side.The diagram visually represents the molecular structure of acetone, illustrating its functional group and connectivity of atoms. Acetone is a simple ketone widely used as a solvent and in the production of plastics and other industrial materials.

Hydrogenation is defined as the chemical reaction between molecular hydrogen and the another element in the presence of catalyst and converts alkene to alkanes. Ozonolysis: is the reaction that takes place when alkenes reacts with ozone in the presence of zinc and results in the formation of carbonyl compounds. Given: • Compound A reacts with one molar equivalent of hydrogen upon catalytic hydrogenation. Hence there is the presence of double bond or alkene. • Compound A is also undergoing ozonolysis reaction hence it is confirmed that there is presence of double bond and upon ozonolysis the compound forma is propanone. therefore, compound A must be 2,3-dimethylbut-2-ene. Hence, compound A is 2,3- Dimethylbut-2-ene. if this answer is helpful to you then do thumbs up as this gives us motivation to solve more and more questions efficiently.
