Chapter 9, Problem 81E

Interpretation Introduction

Interpretation: The condensed structural formula for two different molecules with the formula ${\text{C}}_{\text{3}}{\text{H}}_{\text{4}}\text{O}$ is to be determined.

Concept introduction: The general formula of an aldehyde and a ketone is ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n}}\text{O}$ . The even number of hydrogen atom less than the molecular formula is either due to the formation of double bond or by the formation of cyclic structure.

To determine: The condensed structural formula for two different molecules with the formula ${\text{C}}_{\text{3}}{\text{H}}_{\text{4}}\text{O}$ .
