1. CHEMBIO III:BIOMOLECULES CHEM 221 │ SALGEN,SHRK.

2. Functional group priorities for nomenclature - it is one of the common dilemma in naming a compound is when you encounter a molecule with multiple functional group.

3. Functional group priority list Carboxylic acid Acid anhydride Ester Acid Halide Amide Nitrile Aldehyde Ketone Alcohol Thiol Amine Alkene Alkyne Alkane Ether Thioether Alkyl halide Nitro - from bottom to top, is the increasing order of prioritization for nomenclature.

4. CAN ALL ESTERS ACCOMPANY AMIDES To NAME ALDEHYDES of KATAmines ? No DON’T TRY SAYING it EITHER THEIR ALKYL HALIDES canNOT . CARBOXYLIC ACID ACID ANHYDRIDE ESTER ACID HALIDE AMIDE NITRILE ALDEHYDE KETONE ALCOHOL THIOL AMINE DOUBLE BOND (ALKENE) TRIPLE BOND (ALKYNE) SINGLE BOND (ALKANE) ETHER THIOETHER ALKYL HALIDE NITRO
