Chapter 18.8, Problem 11P

Interpretation Introduction

Interpretation:

The structures of the cyclic acetal or ketal that are derived from each of the given compounds are to be written.

Concept introduction:

Aldehydes and ketones contain carbonyl functional group in their parent chain and are named by adding $\text{suffix }–\text{al}$ and $–\text{one}$ to the name of the parent alkane.

Acetal is type of organic compound with a general formula $\text{RHC}{\left(\text{OR'}\right)}_2$. The two alkoxy groups $\left(\text{OR'}\right)$ are bonded with terminal carbon atom and the $\text{R'}$ group can be same or different.

Ketal is an organic compound with general formula ${\text{R}}_2\text{C}{\left(\text{OR'}\right)}_2$. The two alkoxy groups $\left(\text{OR'}\right)$ are bonded with same carbon atom in between the chain. The $\text{R'}$ and $\text{R}$ groups can be same or different.
