Question

Which of the following statements concerning unsaturated fats is correct?

• A. They have fewer fatty acid molecules per fat molecule
• B. They have double bonds in the carbon chains of their fatty acids
• C. They generally solidify at room temperature
• D. They contain more hydrogen than do saturated fats having the same number of carbon atoms

Answer 1

Answer: (B)

They have double bonds in the carbon chains of their fatty acids

When one or more double bonds are present between the carbon chains of the fatty acids it is known as unsaturated fats. They have a large number of fatty acid molecules per fat molecule. Due to the presence of double bonds they contain a lesser number of hydrogen bonds as compared to the saturated fatty acid molecules.

Hence, the correct answer is 'They have double bonds in the carbon chains of their fatty acids'
