MCQ
Which of the following acyclic compound will react fastest with $Br_2$ gas ?
  • A
    $C_2H_6$
  • ✓
    $C_3H_6$
  • C
    $C_2H_4$
  • D
    $C_2H_2$
✓

Answer

Correct option: B.
$C_3H_6$
b
The compound that will react most readily with gaseous bromine has the formula $\mathrm{C}_{3} \mathrm{H}_{6}$.

Unsymmetrical alkenes generally are more reactive than the symmetrical alkenes, alkynes and alkanes. That is why, propene is more reactive than the other given compounds.
