Which of the following molecule(s)is(are)polar?

Question

Quizplus · Accepted Answer

To determine if a molecule is polar or not, we need to look at its molecular geometry and whether its individual bond dipoles cancel out or not. In option A, COS has a linear molecular geometry and since the O and S atoms have the same electronegativity, the bond dipoles cancel out making the molecule non-polar. In option B, CHS has a trigonal pyramidal molecular geometry and since the S atom has a higher electronegativity than the C and H atoms, the bond dipoles do not cancel out making the molecule polar. In option C, CBr has a linear molecular geometry and since the C-Br bond is polar due to the difference in electronegativity between the atoms, the molecule is polar. In option D, CHBr has a trigonal pyramidal molecular geometry and since the Br atom has a higher electronegativity than the C and H atoms, the bond dipoles do not cancel out making the molecule polar. Therefore, the correct answer is D.
