Lipids exhibit different characteristics based on their structures. The image shows different examples of lipids, such as solid butter and liquid canola oil.

Which type of bond is found in many carbon-to-carbon bonds in canola oil, but very few carbon-to-carbon bonds in butter?
C–C
C=C
C=H
C–H

C=C, carbon-to-carbon double bond is found in Canola.

Explanation:

Canola oil, a vegetable oil, is extracted from the Brassicaceae species, the rapeseed and is a genetically modified product of rapeseed oil.

Canola oil consists of large amounts of polyunsaturated fatty acids (PUFA) with more than one carbon double bonds.

There are about 18 carbon fatty acids present in canola oil. It has high amounts of oleic acid and linoleic acid and less amount of erucic acid. It also high amounts of phytosterols, tocophenols, and polyphenols, which makes it healthy oil.

Butter being a saturated fat has carbon-to-carbon single bond.
