Textbook Problem

If a drop of oleic acid is added to a dish of water, the oleic acid will spread out and form a layer that is one molecule thick on top of the water.

  1. (a) Draw the Lewis structure for oleic acid.
  2. (b) Label the region of the oleic acid molecule that is polar and the region that is nonpolar.
  3. (c) In the layer of oleic acid that forms, which part of the oleic acid molecule points down into the water and which part points out of the water?

(a)

Interpretation Introduction

Interpretation:

The lewis structure for oleic acid has to be drawn.

Concept introduction: Oleic acid is an unsaturated fatty acid. The molecular formula of Oleic acid is CH3(CH2)7CH=CH(CH2)7COOH.

They form lipid bilayer in which polar group is exposed to water and non-polar group points towards the interior of the bilayer.

Explanation

The lewis structure of oleic structure is:

In the lewis structure of oleic acid a linear chain of 18 carbon atoms is present

(b)

Interpretation Introduction

Interpretation:

The structure of oleic acid molecule that is polar and the region that is nonpolar has to be labelled.

Concept introduction: Oleic acid is an unsaturated fatty acid. The molecular formula of Oleic acid is CH3(CH2)7CH=CH(CH2)7COOH.

They form lipid bilayer in which polar group is exposed to water and non-polar group points towards the interior of the bilayer.

(c)

Interpretation Introduction

Interpretation:

In the layer of oleic acid that forms, which part of the oleic acid point downs into the water and which part points out of the water has to be predicted.

Concept introduction: Oleic acid is an unsaturated fatty acid. The molecular formula of Oleic acid is CH3(CH2)7CH=CH(CH2)7COOH.

They form lipid bilayer in which polar group is exposed to water and non-polar group points towards the interior of the bilayer.
