Question

question
some products contain hydrogenated vegetable oils. select which of the following is true.
select all that apply
they have one or more double bonds between the carbon atoms
they have no double bonds between the carbon atoms
they are solid at room temperature
margarine is made with hydrogenated vegetable oil

Explanation:

Step1: Understand hydrogenated vegetable oils

Hydrogenation is the process of adding hydrogen to unsaturated fats (oils). Unsaturated fats have double - bonds between carbon atoms. When hydrogenated, the double - bonds are converted to single bonds.

Step2: Analyze each option

• Option 1: Hydrogenated vegetable oils do not have one or more double bonds between carbon atoms as hydrogenation saturates them. So this is false.
• Option 2: Hydrogenated vegetable oils have no double bonds between the carbon atoms as hydrogenation has saturated them. This is true.
• Option 3: Hydrogenated vegetable oils are solid at room temperature because saturation makes the molecules pack more closely together, increasing the melting point. This is true.
• Option 4: Margarine is made with hydrogenated vegetable oil to give it a more solid consistency. This is true.

Answer:

They have no double bonds between the carbon atoms
They are solid at room temperature
Margarine is made with hydrogenated vegetable oil
