Question

13. Which one of the following statements about intermolecular forces is NOT true? (a) Ion-dipole interactions are strongest for multiply charged ions (Mg*> Na) (b) Hydrogen bonding interactions dramatically raise the boiling point of water in comparison with H2S, H2Se, and H2Te. (c) Hydrogen bonding involves the transfer of a hydrogen from the donor molecule to the acceptor molecule. (d Polarizability increases for large atoms, ions, and molecules versus smaller ones. (e) Strong intermolecular forces increase boiling point and viscosity of solvents 14. What major IR absorption is NOT present for the following compound? ?? (a) O-H at 3000 cm1 (b) sp hybridized C- H at 3300 cm (c) aromatic C-C at 1600, 1500 cm1 (d) carboxylic acid C-O at 1690-1760 cm- (e) aromatic C-H at 3000-3100 cm
