Which of the following has the highest dipole moment?
Ans. A To answer this question, we have to use our intuition. We do not have any specific data on any of the compounds listed as choices. But we can do an intelligent elimination. Choices B and D have the same zero dipole moment. Now it is just a matter of deciding which one of the remaining choices (A and C) is the answer. The electronegativity of fluorine is higher than that of bromine. So HF has the highest dipole moment.
