Why c2h5oh has higher boiling point?
Ethanol (C2H5OH) has a higher boiling point than methane (CH4) because it has stronger intermolecular forces, specifically hydrogen bonding, which requires more energy to overcome and boil. This results in a higher boiling point for ethanol compared to methane.
Does ammonia have a higher boiling point than methane?
Yes, Boiling point of ammonia, NH3: - 33,34 0C Boiling poit of methane, CH4: - 161,6 0C
Which has higher boiling point H2 or He or Ne or Xe or CH4 and why?
Xe has the highest boiling point among the options provided because it has the largest atomic size and the greatest London dispersion forces, which are stronger than the weak van der Waals forces present in the other elements.
Is CH4 volatility?
Methane (CH4) is a gas; the boiling point is at -164 0C.
What has the highest boiling point CH4 CO4 NaCl O2?
NaCl has the highest boiling point. It is an ionic compound with strong bonds between sodium and chlorine ions, requiring more energy to break these bonds and reach the boiling point compared to the other substances listed.
Why does methane have a higher boiling point than Fluromethane?
Metahne does not have a higher boiling point than methane. Fluoromethane, CH3F, has a boiling point of 195K, -78.2C, methane, CH4, has a boiling point of 109K approx -164 C. I make that fluoromethane has a higher temeprature boiling point than methane. This is what you would expect, London dispersion forces will be greater in CH3F as it has more electrons than CH4. CH3F is polar and there will be dipole dipole interactions which will not be present in CH4.

What CH4 boiling point?
CH4's melting point is -182 C. In the context of the usual type of question about melting points, CH4 has a very low melting point because the attractions between CH4 molecules are very weak.
Which has higher boiling point H2 or He or Ne or Xe or CH4 and why?
Xe has the highest boiling point among the options provided because it has the largest atomic size and the greatest London dispersion forces, which are stronger than the weak van der Waals forces present in the other elements.
Is CH4 volatility?
Methane (CH4) is a gas; the boiling point is at -164 0C.
What has a higher boiling point CH3CH3 or CH3Cl?
CH3Cl because it is polar meaning it has both a dipole-dipole bond and dispersion bond, where as CCl4 is non polar and only has a dispersion bond. Since CH3Cl is bonded together stronger, it will be harder to break up and therefore a greater temperature will be required to boil it Edited (9/20/10) CCl4 has a bp 76.7 C, CH3Cl has a bp -24.2 C, see wikipedia or MSDS info. That means the first answer is wrong. Boiling points are based on intermolecular forces. Stronger the forces, lower the vapor pressure, higher the bp. The reason CCl4 has a higher boiling point is because dispersion forces increase with increasing molecular weight and # of electrons. Therefore the greater number of electrons in CCl4 create a stronger dispersion force than the combined dipole+dispersion forces in the CH3Cl.
What has the highest boiling point CH4 CO4 NaCl O2?
NaCl has the highest boiling point. It is an ionic compound with strong bonds between sodium and chlorine ions, requiring more energy to break these bonds and reach the boiling point compared to the other substances listed.
How do The dipole-dipole forces affect the melting and boiling points of substances?
Think relationships here... really London Dispersion Force is like an acquaintance, Dipole Dipole is like boyfriend/girlfriend and Hydrogen Bonding is like marriage. Now out of the three London dispersion is the easiest to break the bonds, Di Pole Di pole are a little harder to break up and Hydrogen bonding are the hardest to break up the bonds. Hydrogen Bonding will always have the strongest bond. London dispersion is when for a split second their is a short attraction and doesn't last long. It is very weak therefore making this non- polar. Dipole Dipole means 2 opposite sides. Positive and negative charges. This molecule is a Polar molecule. Hydrogen Bonding is a Polar molecule which attaches itself to either N,O,or F. A melting point takes a low energy to melt so the bonds are weak. the higher the boiling temperature the stronger the bonds. Think H20. Melting is comparing how hard it is to separate the molecules. Same Concept. Ex.1.) CH4 / LiCl CH4 more soluable / LiCl low soluability CH4 low melting point / LiCL higher melting point CH4 low boiling point/ LiCL Higher boiling point CH4 London Dispersion / LiCl Dipole Dipole Example2: H2O / NaCl H2O high boiling point/ NaCl lower boiling point H2O Hydrogen bonding/ NaCl Dipole Dipol
Which is have highest boiling point Ne N2 O2 Cl2 SiH4?
The boiling point in degree Celsius are given below:Na: 883K: 774Si: 2355Ne: -246Silicon has the highest boiling point among the elements given.
Does CBr4 have a higher boiling point than CCl4?
Yes, CBr4 has a higher boiling point than CCl4 because bromine atoms are larger and heavier than chlorine atoms, leading to stronger van der Waals forces between molecules in CBr4, requiring more energy to break these intermolecular attractions.
Which has a higher boiling point CH3CH3 or CH3NH2?
CH3NH2 has the higher boiling point as it has a hydrogen bond between the molecule which is a stronger intermolecular attractive force, whereas CH3CH3 only has covalent bonds which are weaker intermolecular attractive forces.
