Question
Write the structural formulae for the following IUPAC names: Propan-2-ol
✓
Answer
(1) Propan stands for 3 carbon atoms in a chain. Number the carbon atom in a chain as 1, 2, 3.
$-\stackrel{1}{\mathrm{C}}-\stackrel{2}{\mathrm{C}}-\stackrel{3}{\mathrm{C}}-$
(2) '-ol' stands for $(-\mathrm{OH})$ hydroxyl group. The number assigned for the hydroxyl group is 2 . Show the $-\mathrm{OH}$ group at $\mathrm{C}_2$.
(3) Now satisfy the valencies of each carbon atom
$-\stackrel{1}{\mathrm{C}}-\stackrel{2}{\mathrm{C}}-\stackrel{3}{\mathrm{C}}-$
