... Dmitri Ramzaitsev 11.12.2003 11B Chemistry Laboratory - Boiling Points of Hydrides Data Presentation These tables show the hydrides in the organized in the Groups of the atom the hydrogen is bonded to. Group 4 Compound Boiling Point (°C) CH4 -161 SiH4 -122 GeH4 -90 SnH4 -50 Group 5 Compound Boiling Point (°C) NH3 -33 PH3 -87 AsH3 -60 SbH3 -25 Group 6 Compound Boiling Point (°C) H2O 100 H2S -65 H2Se -45 H2Te -15 Group 7 Compound Boiling Point (°C) HF 20 HCl -85 HBr -96 HI -35 These tables show the hydrides in order of increasing valence electrons of the atom bonding with hydrogen per period. Period 2 Compound Boiling Point (°C) CH4 -161 NH3 -33 H2O 100 HF 20 Period 3 Compound Boiling Point (°C) SiH4 -122 PH3 -87 H2S -65 HCl -85 Period 4 Compound Boiling Point (°C) GeH4 -90 AsH3 -60 H2Se -45 HBr -96 Period 5 Compound Boiling Point (°C) SnH4 -50 SbH3 -25 H2Te -15 HI -35 This table shows the hydrides in increasing order of boiling points. Compound Boiling Point (°C) CH4 -161 SiH4 -122 HBr -96 GeH4 -90 PH3 -87 HCl -85 H2S -65 AsH3 -60 SnH4 -50 H2Se -45 HI -35 NH3 -33 SbH3 -25 H2Te -15 HF 20 H2O 100 This table shows the hydrides in increasing order of valence electrons and increasing quantum energy level. Compound Boiling Point (°C) CH4 -161 NH3 -33 H2O 100 HF 20 SiH4 -122 PH3 -87 H2S -65 HCl -85 GeH4 -90 AsH3 -60 H2Se -45 HBr -96 SnH4 -50 SbH3 -25 H2Te -15 HI -35 Data Analysis and Conclusion To boil something i.e. to get it from a liquid state to a gas state, you need to to separate the atoms or molecules from one another. The temperature or the average kinetic energy of the particles has to be high enough to break the forces that
