Which one of the following molecules has the highest dipole moment ?a)...
Explanation:
Definition of Dipole Moment:
Dipole moment is a measure of the separation of positive and negative charges in a molecule. It is a vector quantity, with both magnitude and direction.
Factors affecting Dipole Moment:
The dipole moment of a molecule depends on the magnitude of the individual bond dipole moments and the molecular geometry.
Analysis of Given Molecules:
- CHCl: In this molecule, the electronegativity of Cl is higher than that of C and H. The bond dipole moment of C-Cl is directed towards Cl, creating a net dipole moment for the molecule.
- CHCl: This molecule is the same as the first one, with the same dipole moment.
- CHCl: In this molecule, the electronegativity of Cl is higher than that of H, resulting in a net dipole moment.
- CCl: In this molecule, both Cl atoms have the same electronegativity. The bond dipole moments cancel each other out, resulting in a net dipole moment of zero.
Highest Dipole Moment:
The molecule CHCl has the highest dipole moment among the given options. This is because the electronegativity difference between Cl and H is greater than that between Cl and C. As a result, the net dipole moment in CHCl is higher compared to the other molecules.
Therefore, option 'B' (CHCl) has the highest dipole moment.
