Question

Liquid fats called oils contain ____________.

1) long CH₂ chains linked by double covalent bonds
2) fat molecules lined up side-by-side
3) many glucose molecules
4) more hydrogen atoms than hard fats

Answer 1

Liquid fats called oils contain long CH₂ chains linked by double covalent bonds.

Step-by-step explanation:

Fats and oils, which are types of lipids, are composed of molecules known as triglycerides. Triglycerides consist of glycerol and fatty acids. The fatty acids in these molecules have long carbon chains and can contain double covalent bonds between carbon atoms. This characteristic of double bonds gives oils their liquid form at room temperature. Therefore, the correct answer is 1) long CH₂ chains linked by double covalent bonds.
