The iodine number of an oil is the mass of iodine, in grams, that will react with 100 g of oil and is a measure of the degree of saturation. Olive oil has an iodine number of 84 and palm oil has an iodine number of 48. Which of the following statements is correct? A. Palm oil is more saturated and has a lower melting point than olive oil. B. Palm oil is more saturated and has a higher melting point than olive oil. C. Palm oil is less saturated and has a lower melting point than olive oil. D. Palm oil is less saturated and has a higher melting point than olive oil.

Step 1

Palm oil is more saturated and has a lower melting point than olive oil.

Answer

This statement is incorrect because a lower iodine number indicates that palm oil is less unsaturated (more saturated) than olive oil. However, saturated fats typically have higher melting points.

Step 2

Palm oil is more saturated and has a higher melting point than olive oil.

Answer

This statement is correct. Since palm oil has a lower iodine number (48) compared to olive oil (84), it means that palm oil is more saturated. Saturated fats usually have higher melting points.

Step 3

Palm oil is less saturated and has a lower melting point than olive oil.

Answer

This statement is incorrect. Palm oil is actually more saturated than olive oil and therefore does not have a lower melting point.

Step 4

Palm oil is less saturated and has a higher melting point than olive oil.

Answer

This statement is incorrect as palm oil is more saturated than olive oil, therefore it cannot have a higher melting point.
