Detailed explanation-1: -In these chains, one or more bonds between the carbon atoms are double. A molecule with one double bond is called monounsaturated, and two or more double bonds is called polyunsaturated. An example of unsaturated fat is vegetable oil.

Detailed explanation-2: -Fatty acids with two or more double bonds occur in lesser quantities, but are extremely important. When double bonds occur they are almost always cis. If there is more than double bond, they occur at three-carbon intervals, e.g., -C=C-C-C=C-. This is called the divinylmethane pattern.
