What is the molecular structure of vegetable oil? what make vegetable oil non-polar?

Vegetable oils are the trigylceride extracted from plants. They have been part of the human life for thousands of years already. The molecular structure of vegetable oil consists of glycerol and fatty acids. Glycerol has 3 carbon atoms and fatty acids are long chain of carbon atoms. Vegetable oil is nonpolar as it can also be dissolved in nonpolar compounds such as gasoline. 

The answer is a) carbon-12

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
