Isopropyl alcohol has a boiling point of 82.3 $\circ$ C. Solutions of isopropyl alcohol in water have normal boiling points less than 100 $\circ$ C. Is this observation consistent with the following equation? Explain.$\Delta$T_b = iK_bm A)No, boiling point elevation only pertains to ionic solutes. B)No, boiling point elevation only pertains to nonvolatile solutes. C)Yes, boiling point depression occurs for all solutions. D)Yes, the boiling point depression constant for isopropyl alcohol is large. E)No, isopropyl alcohol can hydrogen bond with water.

Question

Boiling point elevation pertains to nonvolatile solutes, but in this case, the observation is about boiling point depression, which occurs when a volatile solute like isopropyl alcohol is added to water, lowering the solution's boiling point compared to pure water.
