Select the structures which have a permanent dipole moment?
Options:(select one or more)
Answer:
A, B, C
Solution:
A molecule has permanent dipole moment if its bond dipoles do not cancel due to symmetry.
- (a) Phenol → O–H bond is polar, structure is unsymmetrical → μ ≠ 0
- (b) Dihydroxy benzene → two O–H dipoles do not cancel → μ ≠ 0
- (c) Chlorobenzene → C–Cl bond is polar, unsymmetrical → μ ≠ 0
- (d) p-Xylene (two CH₃ opposite) → symmetric, dipoles cancel → μ = 0
Answer: (a), (b), (c)
