Question

Which of the following molecules has a molecular dipole moment? 
A)1 
B)2 
C)3

Quizplus · Accepted Answer

Molecular dipole moment is observed when there is an uneven distribution of charges within a molecule, which leads to a partial positive and partial negative charge on opposite ends of the molecule. Among the given options, only molecule 2 (HCl) has a polar covalent bond due to the difference in electronegativity between hydrogen and chlorine atoms, resulting in a molecular dipole moment. Molecules 1, 3, and 4 have symmetrical shapes or nonpolar bonds, so there is no molecular dipole moment.
