    \[C{{H}_{3}}C{{H}_{2}}Cl\]undergoes  homolytic fission, produces

    A) \[C{{H}_{3}}\overset{\centerdot }{\mathop{C}}\,{{H}_{2}}\]and \[\overset{\centerdot }{\mathop{C}}\,l\]          

    B) \[C{{H}_{3}}\overset{\oplus }{\mathop{C}}\,{{H}_{2}}\]and \[C{{l}^{\text{o}-}}\]

    C) \[C{{H}_{3}}\overset{\oplus }{\mathop{C}}\,{{H}_{2}}\]and \[\overset{\centerdot }{\mathop{C}}\,l\]

    D) \[C{{H}_{3}}\overset{\centerdot }{\mathop{C}}\,{{H}_{2}}\]and \[C{{l}^{\text{o}-}}\]

    Correct Answer: A

    Solution :

    Key Idea In homolysis, the covalent bond is broken in such a way that each resulting species known as free radical. \[C{{H}_{3}}C{{H}_{2}}-\xrightarrow[fission]{Homolytic}C{{H}_{3}}\overset{\centerdot }{\mathop{C}}\,{{H}_{2}}+{{\,}^{\centerdot }}Cl\]
