Chapter U2.12, Problem 3E

Interpretation Introduction

Interpretation:

A possible structural formula for a molecule with molecular formula C₉H₂₀O having sweet smell must be drawn. The general shape of the molecule needs to be identified.

Concept introduction:

Molecular formula C₉H₂₀O represents alcohols, ethers and aldehyde as all these have 1 O atom in the molecule.

Generally, alcohols have sweet smell.

Answer to Problem 3E

Structural formula of C₉H₂₀O is given below.

CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂OH

The molecule has zigzag shape.

Explanation of Solution

The molecular formula represents three classes of organic compounds which are alcohols aldehyde and ethers. Out of these three classes, alcohols generally have sweet smell which are linear in shape.

Thus, the possible structure will be as follows:
