What is the decreasing order of boiling points for the following liquids: CO2, H2O, NH3, SO2?
A. CO2 > SO2 > NH3 > H2O <\/p>\n\n\n\n

B. NH3 > CO2 > SO2 > H2O <\/p>\n\n\n\n

C. H2O > SO2 > CO2 > NH3 <\/p>\n\n\n\n

D. H2O > NH3 > SO2 > CO2<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is D. H2O > NH3 > SO2 > CO2<\/strong>.<\/p>\n\n\n\n

To understand the decreasing order of boiling points for the given substances\u2014carbon dioxide (CO\u2082), water (H\u2082O), ammonia (NH\u2083), and sulfur dioxide (SO\u2082)\u2014we must consider the intermolecular forces present in each liquid.<\/p>\n\n\n\n

    \n
  1. Water (H\u2082O)<\/strong> has the highest boiling point among these compounds at 100\u00b0C (at 1 atm pressure). This is due to its ability to form extensive hydrogen bonds between its molecules. Hydrogen bonding occurs when hydrogen is bonded to highly electronegative atoms like oxygen, resulting in strong attractions that require significant energy to overcome during the phase change from liquid to gas.<\/li>\n\n\n\n
  2. Ammonia (NH\u2083)<\/strong> has a boiling point of -33\u00b0C. Like water, ammonia also exhibits hydrogen bonding; however, it is weaker than that in water due to the lower electronegativity of nitrogen compared to oxygen. Consequently, while NH\u2083 does have a higher boiling point than substances that exhibit only London dispersion forces, it is lower than that of water.<\/li>\n\n\n\n
  3. Sulfur dioxide (SO\u2082)<\/strong> has a boiling point of -10\u00b0C. The intermolecular forces present in SO\u2082 are primarily dipole-dipole interactions, as the molecule is polar. While these interactions are stronger than the London dispersion forces present in nonpolar molecules, they are generally weaker than hydrogen bonds. Thus, SO\u2082 has a higher boiling point than CO\u2082 but lower than NH\u2083 and H\u2082O.<\/li>\n\n\n\n
  4. Carbon dioxide (CO\u2082)<\/strong> has a boiling point of -78\u00b0C and is a nonpolar molecule. The intermolecular forces in CO\u2082 are limited to London dispersion forces, which are the weakest type of intermolecular interaction. This results in CO\u2082 having the lowest boiling point among the four substances.<\/li>\n<\/ol>\n\n\n\n

    In summary, the boiling points are primarily influenced by the type and strength of intermolecular forces present in each substance, leading to the order: H\u2082O > NH\u2083 > SO\u2082 > CO\u2082<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
