I need help on 6,7, and 8 please!

cicetone mas mare phan ether. Therefore afpoer interachon Which Stronger than dipole-dip 6. Carbon tetrachloride, CCla, was once used as a dry cleaning solvent, but is no longer used of because it is carcinogenic. At 57.8 °C, the vapor pressure of CCla is 54.0 kPa, and its enthalpy vaporization is 33.05 kJ/mol. Use this information to estimate the normal boiling point for CCl. 7. Explain why the enthalpies of vaporization of the following substances increase in the order CH4< NH3 < H2O, even though all three substances have approximately the same molar mass. 8. The hydrogen fluoride molecule, HF, is more polar than a water molecule, H:0 (for example, has a greater dipole moment), yet the molar enthalpy of vaporization for liquid hydrogen fluoride is lesser than that for water. Explain.
