Why do the boiling points of H2O and HF deviate? A. F and O and both found in the second period. B. The size of H2O and HF are small relative to those of the other molecules. C. H2O and HF are less polarizable than the other molecules. D. H2O and HF can hydrogen bond. ANS - D What type of intramolecular bonding occurs in MgCl2? A. Covalent B. Ionic C. Hydrogen D. Dipole-induced dipole ANS - B Why do the boiling points of the noble gases increase as the period increases? A. The bonds are stronger because larger atoms are more polarizable as period increases. B. The bonds are weaker because larger atoms are more polarizable as period increases. C. The bonds are stronger because larger atoms are less polarizable as period increases. D. The bonds are weaker because larger atoms are less polarizable as period increases. ANS - A What type of intermolecular bonding occurs in gaseous CH4 A. Covalent bonding B. Ionic bonding C.
