Isopropyl Alcohol Has a Boiling Point of 82 $\circ$ CSolutions of Isopropyl Alcohol in Water Have Normal Boiling Points

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 pertains only to ionic solutes.
B) No,boiling point elevation pertains only 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.
