The CORRECT statement for CH 3 - X ( X = F , Cl , Br , l ) is

CH 3 - F has highest CH 3 - X bond enthalpy and lowest dipole moment

CH 3 l has lowest CH 3 - X bond enthalpy and lowest dipole moment

CH 3 - Br has highest CH 3 - X bond enthalpy and highest dipole moment

CH 3 - Cl has highest CH 3 - X bond enthalpy and CH 3 - Br has highest dipole moment

For the compounds CH 3 Cl, CH 3 Br, CH 3 I and CH 3 F, the correct order of increasing C-halogen bond length is :

CH 3 F < CH 3 Cl < CH 3 Br < CH 3 I

CH 3 F < CH 3 Br < CH 3 Cl < CH 3 I

CH 3 F < CH 3 I < CH 3 Br < CH 3 Cl

CH 3 Cl < CH 3 Br < CH 3 F < CH 3 I
