Current Question (ID: 17665)

Question:
$\text{The compound that will react most readily with gaseous bromine has the formula:}$
Options:
  • 1. $\text{C}_3\text{H}_6$
  • 2. $\text{C}_2\text{H}_2$
  • 3. $\text{C}_4\text{H}_{10}$
  • 4. $\text{C}_2\text{H}_4$
Solution:
$\text{Hint: The reaction is an example of free radical substitution reaction}$ $\text{When alkene reacts with gaseous bromine in the presence of light then free radical substitution reactions occur.}$ $\text{The rate of free radical substitution reaction depends on the stability of free radical.}$ $\text{The radicals formed by the given compounds are as follows:}$ $\text{H}_2\text{C}=\text{C}-\text{CH}_3 \rightarrow \text{Resonance stabilized}$ $\text{HC} \equiv \text{CH} \rightarrow \text{No reaction (radical does not form)}$ $\text{H}_2\text{C}-\text{C}-\text{CH}_3 \rightarrow \text{stabilized by resonance}$ $\text{H}_2\text{C}=\text{CH}_2 \rightarrow \text{No reaction (radical does not form)}$ $\text{Only C}_3\text{H}_6 \text{ form the most stable free radical hence the rate of reactivity of C}_3\text{H}_6 \text{ is the highest.}$
