How To Name A Compound With Multiple Functional Groups Chemistry Steps Step 3. number the parent chain starting from the highest priority group and add the substituent (s) alphabetically: it is also noteworthy that if there is a functional group suffix and a substituent, the functional group suffix gets the lowest possible number. for example, alcohols have higher priority than amines and therefore, when naming a. Table 2.4 subordinate groups. we will go through several examples for more details about the naming rules. 1. the parent structure is the 6 carbon carboxylic acid with a double bond, so the last name comes from “hexene”. to add the suffix, the last letter “e” will be dropped, so the parent name is “hexeneoicacid”.
How To Name A Compound With Multiple Functional Groups Chemistry Steps To name a compound with multiple functional groups, we need to identify the functional group with the highest priority. this group defines the suffix of the. Identify the functional groups (other than alkanes) in the following organic compounds. state whether alcohols and amines are primary, secondary, or tertiary. solutions to exercises. a) carboxylate, sulfide, aromatic, two amide groups (one of which is cyclic) b) tertiary alcohol, thioester. c) carboxylate, ketone. Functional groups are structural units within organic compounds that are defined by specific bonding arrangements between specific atoms. for example the structure of capsaicin, found in chili peppers, incorporates several functional groups, labeled in the figure below and explained throughout this section. even if other parts of the molecule. 3. lowest sum rule. 4. alphabetical order rule (naming of substituents) 5. complex alkyl substituent rule. 6. multiple functional group rule. priority order of functional groups in iupac nomenclature.

These groups include the halides (bromo, chloro, fluoro, iodo), ethers (“alkoxy”), azide and nitro functional groups. source: table 5.1, section p 59.1.9 of the 2013 blue book (page 630). some examples with multiple functional groups. here are some examples of applying the order of functional group priorities to solve nomenclature problems. If a side chain or lower priority functional group appears more than once in a compound, then a multiplying affix (“di ,” “tri ,” “tetra ,” etc.) should be added to the prefix. for example, a compound containing 3 methyl groups will use the prefix “trimethyl .” step 6: number the parent chain.
