How to name organic compounds in chemistry, such as positive and negative.

The naming of organic compounds is a systematic naming method. Mastering this method, general organic compounds can be named.

The system naming rule is 1, and the matrix (functional group) is determined. 2. Select the main chain (the longest carbon chain containing functional groups); 3. Number (near the functional group number); 4. Fill in the full name (write down the name, quantity, grade and functional group grade of substituents before the parent name, and finally the parent). See the following example.

(CH3)2CHCH2CH2COOH, whose name is 4- methylvaleric acid. Take a look at the naming rules.
