Question
Write the structural formulae for the following IUPAC names: 1-Bromopropane.
✓
Answer
(1) In 1-bromopropane, propane is parent alkane stands for 3 carbon atoms and number the carbon atoms in a chain as 1, 2, 3…….
$\stackrel{3}{\mathrm{C}}-\stackrel{2}{\mathrm{C}}-\stackrel{1}{\mathrm{C}}$
(2) Bromo (Halo) is the prefix and the number assigned for prefix (bromo) is 1 , show the bromine atom at $C_1$.
$
\stackrel{3}{\mathrm{C}}-\stackrel{2}{\mathrm{C}}-\stackrel{1}{\mathrm{C}}-\mathrm{Br}
$
(3) Now satisfy the valencies of each carbon atom
$\stackrel{3}{\mathrm{C}}-\stackrel{2}{\mathrm{C}}-\stackrel{1}{\mathrm{C}}$
