Discover the World of Ethers in Chemistry By Anne Marie Helmenstine, Ph.D. Fats and oils are examples of esters. The difference between them is the melting point of their esters. If the melting point is below room temperature, the ester is considered to be an oil (such as vegetable oil...
Thou in organic chemistry a substituent is usually a group replacing an hydrogen attached to a carbon atom, this can be further generalized if it helps you explain a given trend. For example, you could define a series of compounds where R = "HO" and X = H, CH3, COCH3, and analyze ...
