- a)methyl chloride
- b)carbon tetrachloride
- c)methylene chloride
- d)chloroform
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
The compound with no dipole moment is (1982 - 1 Mark)a)methyl chloride...
TIPS/Formulae : (i) Dipole moment is vector quantity. When vector sum of all dipoles in molecule will be zero, then molecule will not have net dipole moment.
(ii) NOTE : For net dipole moment to be equal to zero, all the atoms attached to central atom must be identical and geometry must be regular.
(ii) NOTE : For net dipole moment to be equal to zero, all the atoms attached to central atom must be identical and geometry must be regular.
∴ Carbon tetrachloride having regular geometry and identical atoms attached to bonds has zero dipole moment.

Understanding Dipole Moments
A dipole moment occurs in a molecule when there is a separation of positive and negative charges due to differences in electronegativity between atoms. Molecules with symmetrical structures often exhibit no net dipole moment, despite the presence of polar bonds.
Analyzing the Compounds
- Methyl Chloride (CH3Cl)
- This molecule has a C-Cl bond, which is polar. The asymmetrical shape leads to a net dipole moment.
- Carbon Tetrachloride (CCl4)
- CCl4 is a tetrahedral molecule with four identical C-Cl bonds. The symmetrical arrangement of these polar bonds leads to the cancellation of dipole moments, resulting in no net dipole moment.
- Methylene Chloride (CH2Cl2)
- With two polar C-Cl bonds and an asymmetrical arrangement, this molecule has a net dipole moment.
- Chloroform (CHCl3)
- Chloroform has one hydrogen atom and three polar C-Cl bonds. Its asymmetrical shape leads to a net dipole moment.
Conclusion
The correct answer is option 'B' - Carbon Tetrachloride (CCl4). Its symmetrical tetrahedral geometry allows the individual bond dipoles to cancel each other out, resulting in no overall dipole moment. This characteristic makes CCl4 a nonpolar molecule, while the other choices have structures that lead to a net dipole.
