Interpretation Introduction

(b) Interpretation:

The structure of 18:1cΔ11 should be drawn.

Concept Introduction:

The 18:1cΔ11 fatty acid is a monounsaturated fatty acid, in this the number 18 depicts the number of carbon atoms in the linear chain, 1 represents a single unsaturation site, cΔ11 represents the presence of unsaturation at the 11th carbon.

Interpretation Introduction

(c) Interpretation:

The structure of a saturated fatty acid that should melt below 300C should be drawn.

Concept Introduction:

The fatty acids having a lighter chain tends to melt at a lower temperature. Increase in the number of carbons increases the melting point of the fatty acids. The n-octanoic acid is well known to melt at a temperature of 16-170C.

Expert Solution
Check Mark

Explanation of Solution

The structure of n-octanoic acid having a melting point 16-170C is depicted in the figure given below:
