Organic nomenclature questions test an orderly procedure. Circle the functional group, choose the longest parent chain containing it, number from the appropriate end, identify and alphabetise substituent names where required, then write the suffix and location. Translate the final name back into a structure as a check: each carbon should have four bonds, the functional group should occupy the stated position and total carbon count should match. When an answer includes a reaction, distinguish the organic substrate from reagent or catalyst so the name is assigned to the correct molecule.
Work it through
For CH₃CH₂CH(Br)CH₃, the parent chain is butane. Numbering from the closer end gives the bromo substituent position 2: 2-bromobutane. A name like 3-bromobutane describes the same connectivity but violates the lowest-number convention. The check is to redraw the named structure.
Mastery target
