Detailed explanation-1: -Answer and Explanation: Vegetable oils, such as corn oil, belong to the B) lipid class of organic substances. This is because vegetable oils are primarily composed of triglycerides, which are lipids made up of three individual fatty acids covalently linked to a glycerol backbone.

Detailed explanation-2: -Vegetable oils are mainly triacylglycerols (92–98%), polar lipids (phospholipids and galactolipids), monoacylglycerols, diacylglycerols, and minor amounts of free fatty acids and polyisoprenoids.

Detailed explanation-3: -Refined corn oil is composed of 99% triacylglycerols with polyunsaturated fatty acid (PUFA) 59%, monounsaturated fatty acid 24%, and saturated fatty acid (SFA) 13%. The PUFA is linoleic acid (C18:2n-6) primarily, with a small amount of linolenic acid (C18:3n-3) giving a n-6/n-3 ratio of 83.

Detailed explanation-4: -INTRODUCTION: Vegetable oils are composed of triglycerides. The triglycerides are molecules that contain carbon, hydrogen and oxygen, and its structure includes glycerol and three fatty acids. The fatty acids present in triglycerides may be the same or of different types.

Detailed explanation-5: -The simplest class of organic compounds is the hydrocarbons, which consist entirely of carbon and hydrogen. Petroleum and natural gas are complex, naturally occurring mixtures of many different hydrocarbons that furnish raw materials for the chemical industry.
