Question
Classify the following compounds as primary, secondary and tertiary halides.
  1. 1-Bromobut-2-ene
  2. 4-Bromopent-2-ene
  3. 2-Bromo-2-methylpropane
✓

Answer

  1. 1-Bromobut-2-ene
$\text{CH}_3-\text{CH}=\text{CH}-\text{CH}_2-\text{Br}...(\text{primary halide})$
  1. 4-Bromopent-2-ene
$\text{CH}_3-\text{CH}=\text{CH}-\text{CHBr}-\text{CH}_3...(\text{Secondary halide})$
  1. 2-Bromo-2-methylpropane
$(\text{CH}_3)_3\text{CBr}...(\text{tertiary halide})$
