Answer:
The correct answer would be : carbon = carbon (double bonds between carbons)
Explanation:
Linoleic acids is a non polar polymer of unsaturated fatty acid (omega 6) made up of a polymer of 18 carbon chain. This unsaturated fatty acid have single bond in its structure but there few double bonds (already highlighted in question image).
These double bonds are makes twists or bend in the chains of fatty acid. These bends known as kinks formed by double bonds. Number of kinks increase the twist and bend in the fatty acid molecule.
Thus, the correct answer would be : carbon = carbon (double bonds between carbons)
