Systematic Naming of Cyclic Compounds

1) Identify the parent chain, that is, the longest carbon chain, and name the molecule based on it.

2) Number all carbon atoms in the parent chain starting from the end nearest to a group with the highest priority.

3) List all substituent groups in alphabetical order.

4) For substituent alkanes, replace the suffix -ane with -yl.

5) For halogenated compounds, use the prefixes chloro-, bromo-, fluoro-, and iodo-.

6) For alcohols, that is, compounds with a hydroxyl group (-OH group) attached to it, replace the e in the suffix -ane with -ol.

7) For compounds with multiple functional groups, the order of priorities is to be observed in decreasing order: carboxylic acids, nitriles, aldehydes, ketones, alcohols, amines, alkenes, alkynes, halides.
