Textbook Question
Chapter 24, Problem 20PS
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.
- (a) Draw the Lewis structure for oleic acid.
- (b) Label the region of the oleic acid molecule that is polar and the region that is nonpolar.
- (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?

If the molecule or polyatomic ion is polar, write the chemical symbol of the atom closest to the negative side.
Decide whether each molecule or polyatomic ion
is polar or nonpolar.
If the molecule or polyatomic ion is polar, write
the chemical symbol of the atom closest to the
negative side. For example, if the molecule were
HCI and you decided the hydrogen atom was
closest to the negative side of the molecule,
you'd enter ":" in the last column of the table.

- What is the most polar bond in the molecule?arrow_forwardWater is considered the solvent of life. Water's polarity makes it unique, and this polarity is responsible for the life giving properties of water. In this short essay question, answer only one of the following questions, A OR B. In your first sentence, tell me if your answer is for A or B. NOTE that saying "water is polar, so it is cohesive", or "water is polar, so it moderates temperature", or "water is polar, so is more dense as liquid", with a description of how that life giving property is beneficial to life, does NOT answer this question! You must explain, in your OWN words, HOW the polarity of the water is mechanistically responsible for the life giving property you choose. Question B: Explain in detail how the polar nature of water allows fish to survive and swim around in the watery depths of Lake Baikal, Russia, all winter long in spite of the average air temperatures of minus 25 degrees Celsius in this frozen, snow covered region.

(b) If the difference in electronegativity between two atoms is zero (they have identical electronegativ- ities), then the two atoms will not form a covalent bond. (c) A covalent bond formed by sharing two electrons is called a double bond. (d) In the hydrogen molecule (H2), the shared pair of electrons completes the valence shell of each hydrogen. (e) In the molecule CH4 , each hydrogen has an electron configuration like that of helium and carbon has an electron configuration like that of neon.
