Which of the following shows an unsaturated fatty Acid? Out of those two
SVETLANKA909090 [29]

Answer:

None of these two

Explanation:

An unsaturated fatty acid must contain a double bond in the poly carbon chain other than the double bond in the functional group. In these two, images there exists a double bond in the carboxylic group i.e –COOH.  

Since none of them have double bond in long poly carbon chain, therefore these two fatty acids cannot  be considered as unsaturated fatty acid.
