Some Good Examples and Nature of C-X Bonds
i) Give the IUPAC names of following compounds :-
i) Give IUPAC names of following Haloarenes:-
NATURE OF THE C – X BOND:-
- Due to the electronegativity difference b/w the highly electronegative chlorine atom and less electronegative alkyl group
Halogen attains a partially negative charge and alkyl group attains +ve charge.
- The size of halogen atom increase as we move down the group. Consequently carbon – halogen bond length increase and bond enthalpy decreases
From C – F to C – I
- From F to I electronegativity of halogen decreases hence dipole moment of C –X bond decreases.
