Question

The compound zoapatanol was isolated from the leaves of a Mexican plant.

Classify each oxygen in zoapatanol according to the functional group to which it belongs. If an oxygen is part of an alcohol, classify the alcohol as primary, secondary, or tertiary.

Answer 1

The structure is shown below!

1. Ketone

2. Secondary alcohol

3. Ether

4. Primary alcohol

Step-by-step explanation:

The molecule of zoapatanol is shown below, each oxygen is marked by a number. The functional group represents the organic function of the substance. Some substances can have more than one function.

The oxygen is presented in several organic compounds, such as alcohol, aldehyde, ketone, ether, ester, carboxyl acid, and others. The structure of each is different, so an alcohol has the oxygen bonded to a carbon and to a hydrogen (called hydroxyl); an aldehyde has the oxygen bonded to a terminal carbon; a ketone has the oxygen bonded to nonterminal carbon; the ether has an oxygen between carbons; the ester has an oxygen between carbons, and one of these carbons has a double bond with other oxygen, and a carboxyl acid has the terminal carbon bonded to an oxygen and to a hydroxyl.

If the hydroxyl is bonded to a primary carbon (which is bonded to only one carbon), then it's a primary alcohol, if it's bonded to a secondary carbon (which is bonded to 2 carbons), then it's a secondary alcohol, and if it's bonded to a tertiary carbon (which is bonded to 3 carbons), then it's a tertiary alcohol.

Analyzing the structure, the oxygens are:

1. Ketone

2. Secondary alcohol

3. Ether

4. Primary alcohol
