WebIn organic chemistry, the most common functional groups are carbonyls ( C=O C=O ), alcohols ( -OH -OH ), carboxylic acids ( CO2H CO 2 H ), esters ( CO2R CO 2 R ), and amines ( NH2 NH 2 ). It is important to be able to recognize the functional groups and the physical and chemical properties that they afford compounds. Web25 jan. 2024 · Ans: Following are the rules for writing naming organic compounds. Rule 1: Find the longest continuous chain of carbon atoms and use its name as the base name for the compound. Rule 2: Beginning with the end of the chain closest to a substituent, number the longest chain.
