What force exists between H2O and  CH3CH2OH? Is it Ion-dipole?

7. Electronegativity All about ammonia (NH3). Sb (antimony, atomic #51,) is in same Periodic Table column as N. The boiling point of SÜH3 (stibine, -17 °C) is slightly higher than NH3 (-33 °C). H 2.1 N 3.0 Sb 2.1 7a. What kinds of intermolecular interactions would occur in NH3 (1)? What kinds of intermolecular interactions would occur in SbH3 (1)? Is it surprising or expected that stibine would have a higher boiling point than ammonia? What could account for this higher boiling point?

Which would you expect to have the highest melting point? 1. RbCl 2. KCI 3. They have the same melting point Because 4. The internuclear distance is smaller; therefore, the force is stronger and requires more energy to overcome. 5. The charge is higher; therefore, interactions are stronger and require more energy to overcome. 6. They have the same charge and internuclear distance; therefore, interactions are of the same strength and require the same amount of energy to overcome. O 3 and 5 O 1 and 5 2 and 5 MacBook Air DII DD O00
