Q 1 :    

The correct sequence of bond enthalpy of 'C-X' bond is           [2021]

  • CH3-Cl>CH3-F>CH3-Br>CH3-I

     

  • CH3-F<CH3-Cl<CH3-Br<CH3-I

     

  • CH3-F>CH3-Cl>CH3-Br>CH3-I

     

  • CH3-F<CH3-Cl>CH3-Br>CH3-I

     

(3)

The correct order of bond enthalpy is  

CH3-F>CH3-Cl>CH3-Br>CH3-I
