Did you know?
WebFor example, consider group 6A hydrides: H2O, H2S, H2Se, and H2Te. Among these hydrides, the molar mass increases in the following order: H2O < H2S < H2Se < H2Te Therefore, the boiling point of H2O is expected to be the lowest. However, it is observed that the boiling point of H2O is highest among these hydrides. WebThe hydrides of group 5A are NH3, PH3, AsH3, and SbH3. Arrange them from highest to lowest boiling point. Steps 2 and 3. Step 2: Arrange the group 5A hydrides PH3, SbH3, …
