Answer:
c). In which the hydrogen attached to adjacent carbons in a carbon-carbon double covalent bond are on opposite sides of the molecule.
Explanation:
Trans fatty acids have double bonds. The hydrogen attached to adjacent carbons in a carbon-carbon double covalent bond are on opposite sides of the molecule.
Cis fatty acids have double bonds. The hydrogen attached to adjacent carbons in a carbon-carbon double covalent bond are on the same side of the molecule.
Add Answer to:
1. A trans fatty acid is one a. that has no carbon-carbon double bonds directly adjacent...
