Chapter 11.2, Problem 11.2YT

(a)

Interpretation Introduction

Interpretation:

The line-angle drawing for palmitic acid has to be drawn.

Line-angle drawing:

• • The structure of a molecule can be represented using a line-angle drawing.
• • Each vertex is assumed to have one carbon atom.
• • If a line is extended from the backbone indicates another carbon atom which will be a methyl group unless the symbol for another element is given.
• • In line-angle drawing, hydrogen atoms are not indicated.

(b)

Interpretation Introduction

Interpretation:

The functional group responsible for the acidic properties of fatty acids has to be named.

Concept introduction:

Fatty acids are aliphatic mono-carboxylic acids that are mostly obtained from the hydrolysis of natural fats and oils. They have a general formula $R-{\left(C{H}_2\right)}_n-COOH$, n is mostly an even number of carbon atoms (4 to 20) with a few exceptions that have an odd number.
