Question
Which of the following compounds have highest dipole moment?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Dichloromethane (CH2Cl2) has the highest dipole moment among the given chloromethanes. The vector sum of two C-Cl bonds results in a larger dipole than a single C-Cl bond in chloromethane, while the symmetrical CCl4 has zero dipole, and chloroform has a smaller resultant dipole than dichloromethane.
Hint
Consider the vector sum of the individual bond dipoles in each molecule.
