Does Sulfur hexafluoride have a permanent dipole?
What is no?
Which of the following has the higher boiling point and why: phenol (C₆H₅OH) or anisole (C₆H₅OCH₃)?
What is Phenol has the higher boiling point because it can form strong hydrogen bonds, while anisole can only participate in dipole–dipole and London dispersion forces.
