Chapter 20, Problem 4P

(a)

Interpretation Introduction

Interpretation: The shorthand nomenclature of lauric acid should be drawn and whether it is saturated or unsaturated should be determined.

Concept Introduction: A long and unbranched carbon chain that consists carboxyl group attached at one end of the chain is said to be fatty acid. The fatty acids that contain only single bond between carbon atoms are said to be saturated whereas unsaturated fatty acids have one or more carbon-carbon double bond(s) in the fatty acid chain.

In shorthand description of fatty acids, the number of carbon atoms are written first followed by number of double bond(s) between carbon atoms separated by colon.

(b)

Interpretation Introduction

Interpretation: The shorthand nomenclature of oleic acid should be drawn and whether it is saturated or unsaturated should be determined.

Concept Introduction: A long and unbranched carbon chain that consists carboxyl group attached at one end of the chain is said to be fatty acid. The fatty acids that contain only single bond between carbon atoms are said to be saturated whereas unsaturated fatty acids have one or more carbon-carbon double bond(s) in the fatty acid chain.

In shorthand description of fatty acids, the number of carbon atoms are written first followed by number of double bond(s) between carbon atoms separated by colon.

(c)

Interpretation Introduction

Interpretation: The shorthand nomenclature of linolenic acid should be drawn and whether it is saturated or unsaturated should be determined.

Concept Introduction: A long and unbranched carbon chain that consists carboxyl group attached at one end of the chain is said to be fatty acid. The fatty acids that contain only single bond between carbon atoms are said to be saturated whereas unsaturated fatty acids have one or more carbon-carbon double bond(s) in the fatty acid chain.

In shorthand description of fatty acids, the number of carbon atoms are written first followed by number of double bond(s) between carbon atoms separated by colon.

(d)
