DEFM200 Assign P-O OP-S OP-N 5 pts
Question 29 Grand Forks.... Advantages and Dis.... DEFM200 Assignm Which of the following best explains the difference in boiling point between HCl and HB? OHCI has the higher boiling point because HCI has hydrogen bonding and HBr does not OHBr has the higher boiling point because HBr has stronger London-dispersion forces than HC OHBr has the higher boiling point because HBr has stronger dipole-dipole forces than H OHCI has the higher boiling point because HCI has stronger dipole-dipole forces than O HCI has the higher boiling point because HCI has stronger London-dispersion forces than
