Pick up the character which does not belong to unsaturated fatty acids:
Correct answer: A. No double bond
- A. No double bond
- B. Presence of multiple double bonds
- C. Low melting point
- D. Commonly found in plant fats
Explanation
The correct option is A) No double bond. Unsaturated fatty acids are defined by the presence of one or more double bonds in their carbon chains. This structural characteristic differentiates them from saturated fatty acids, which do not have double bonds. Option B) Presence of multiple double bonds, Option C) Low melting point, and Option D) Commonly found in plant fats are all properties associated with unsaturated fatty acids, hence they do belong to this category.
