Question

What about SF4 and NO . I made mistake on them.

U AB 2018 2. For the following ions/molecules, describe the strongest intermolecular forces present? (4 pts, choices are ion-dipole, H- bonding, LDF, dipole-dipole) et LDF 8 +(4 x 7) = 36 SF. Ion-dipole 76+ (4x7) = 34 é NO₂ (aq) Dipoler-dipole 10 H-bonding

and SF3 and NO3

Answer 1

* Sty I lone pair polar F Soz is trigonal planar, E - Individual dipoles on. S-o bonds cancel and molecule has no dipole moment. * but in Sfy The unsymmetrical See-saw shape beads to high dipole moment but cancies each other along all & directions and becomes Zero. It has one unpair electron on Nitrogen, and the dipole forces exist in opposite direction on both oxygen atoms. This The intermolecular force is in- dipole in the No, due to its structure * It has two resonance structures
