Carbon is an unusual atom in that it can form multiple bonds. Which statement is NOT true? a) A carbon-to-carbon cis double bond is the type found in nature and is associated with cardiovascular health. b) A carbon-to-carbon trans double bond is made artificially in food processing and is associated with poor cardiovascular health. c) Multiple carbon-to-carbon double bonds located near each other can absorb light, so they are found in molecules in the eye or in chloroplasts. d) Multiple carbon-to-carbon bonds are stronger than single bonds. e) Saturated fats are those that have a carbon-to-carbon double bond are associated with good health. © 2014 Pearson Education, Inc.
