Question

identify the unsaturated fatty acid.
select the correct answer below:
ho - c - c - c - c - c - c - c - c - c = c - c - c - c
ho - c - c - c - c - c - c - c - c - c = c - c - c - c
h - o - c - c - c - c - h
all of the above

Explanation:

Unsaturated fatty acids have one or more double bonds in their carbon - chain. The first two structures have a \(C = C\) double bond, which is characteristic of unsaturated fatty acids. The third structure is a short - chain ester (not a fatty acid). Since not all options are valid (the third one is not a fatty acid), the “all of the above” option is incorrect.

Answer:

The first two options (assuming they are the ones with \(C = C\) double bonds in their carbon - chain structures) are unsaturated fatty acids.
