due to Hydrogen bonding in liquid state.The B.p of SbH3 is still higher due to high extent of van der waal forces. The Questions and Answers of The order of boiling point among NH3 PH3 AsH3 SbH3 BiH3? Boiling point is related to intermolecular forces. The hydrides of group 5A are NH3, PH3, AsH3, and SbH3. AsH3 comes first because it has a smaller atomic radii, therefore making it a more compacted molecule and harder to break apart. Preparing for entrance exams? All of these compounds are nonpolar and only have London dispersion forces: the larger the molecule, the larger the dispersion forces and the higher the boiling point. The points i have been given are NH3 boiling point = -33°C PH3 = -88°C AsH3 = -62°C and SbH3 = -17°C NH3 is a predominantly a hydrogen bond therefore, it has the highest boiling point of these compounds. The hydrides of group 5A are NH3, PH3, AsH3, and SbH3. Explain why the boiling point of PH3 is lower than the boiling point of AsH3. Which of the following is a tribasic acid? The hydrides of group 5A are NH3, PH3, ASH3, and SBH3. I have a graph which shows the boiling points of the hydrides of group 5. Which of the following processes is endothermic? Points, Bp of NH3: -33°C , PH3: -87°C , AsH3: -62.4°C , SbH3: -18°C, So the increasing order of boiling point is, The regular trend for boiling point is that it increases down the group due to increase in size and van der waal forces between atoms.But the B.p of ammonia(NH3) is more than Ph3 and Ash3. Bigger molecules will have stronger London dispersion forces. I have a graph which shows the boiling points of the hydrides of group 5. Pay Now |
