Chapter 24, Problem 11STP

Interpretation Introduction

Interpretation: To state whether the given statement is true or false.

Concept Introduction: Lipids are chemical substances. The nature of these substances is non-polar.

Answer to Problem 11STP

Statement II is the correct explanation for statement I.

Explanation of Solution

The lipids are insoluble in water due to the presence of non-polar bonds.

Lipids are fats, oils, and other compounds that are water-insoluble. Natural fats and oils are triesters of glycerol along with fatty acids (long-chain carboxylic acid). These lipids are termed a triglyceride.

A lipid is composed of two parts that are as follows:

• Hydrophilic head
• Hydrophobic tail

The head is hydrophilic i.e., water-loving in nature while the tail is hydrophobic i.e., water-hating.

The lipids are insoluble in water due to the presence of non-polar bonds while they are soluble in non-polar solvents.

Conclusion

Hence, statement II is the correct explanation for statement I.
