Explain the nature of C - X bond in alkyl halides. |
Answer» Solution :Halogen atoms are more electronegative than carbon, therefore, carbon - halogen BOND of alkyl halide is polarised, the carbon atom bears a partial positive charge WHEREAS the halogen atom bears a partial negative charge. As we go down the group in the PERIODIC table, the SIZE of halogen atom is the smallest and iodine atom is the LARGEST. Consequently the carbon - halogen bond length also increases from C - F to C - I.  Order of dipole moment : `CH_(3)Cl gt CH_(3)F gt CH_(3)Br gt CH_(3)I` Order of bond enthalpies : `CH_(3)F gt CH_(3)Cl gt CH_(3)Br gt CH_(3)I` |
