Chapter 16, Problem 1PP

PRACTICE PROBLEM 16.1

(a) Give IUPAC substitutive names for the seven isomeric aldehydes and ketones with the formula $C_5{H}_{10}O$.

(b) Give structures and names (common or IUPAC substitutive names) for all the aldehydes and ketones that contain a benzene ring and have the formula $C_8{H}_{8}O$.

Interpretation Introduction

Interpretation:

For the given molecular formula, ${\text{C}}_{\text{5}}{\text{H}}_{\text{10}}\text{O}$, the IUPAC substitutive names for the seven isomers of aldehydes and ketones are to be written. Further, for the molecular formula, ${\text{C}}_{\text{8}}{\text{H}}_{\text{8}}\text{O}$, the structures and the names (either common or substitutive names) for all the aldehydes and ketones containing a benzene ring are to be given.

Explanation of Solution

Given information: ${\text{C}}_{\text{5}}{\text{H}}_{\text{10}}\text{O}$

The molecular formula is ${\text{C}}_{\text{5}}{\text{H}}_{\text{10}}\text{O}$. In ${\text{C}}_{\text{5}}{\text{H}}_{\text{10}}\text{O}$, there are five carbon atoms, ten hydrogen atoms, and one oxygen atom. The seven isomeric aldehydes and ketones are as follows:

The IUPAC name is as follows:
