Ammonia has a higher boiling point then methane because it is a polar molecule, meaning that one part of the molecule has a partial positive charge while the other has a partial negative charge. As a result, ammonia molecules are attracted to each other in a similar manner as magnets are.

Methane, dues to its symmetry, is nonpolar.

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


Why do ammonia has higher melting and boiling point than methane?

Ammonia (NH3) has hydrogen bonding intermolecular forces, whereas methane (CH4) does not. In addition, ammonia is polar, and so also has dipole-dipole forces and methane does not. Thus, it takes more energy (higher temperature) to boil and melt ammonia than it does methane.


Why is boiling point of ethanol higher than its isomer methane?

Boiling point of ethanol is higher than its isomer methane due to the presence of hydrogen bond in ethanol


Which substance has higher boiling point nitrogen fluoride or NH3?

Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.


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.


Why does ammonia have a much higher boiling point than methane?

Ammonia is a strongly polar molecule with a positively charged end and a negatively charged end on each molecule. The creates a strong attractive force between molecules that greatly raised the boiling point. Methane is nonpolar, so the attractive forces between molecules are much weaker.


What is the boiling point of methane in Fahrenheit?

The boiling point of Methane is 83F


Why does water have a higher boiling point than methane?

Water has stronger hydrogen bonds than Methane. More energy is required to break them, hence the difference in boiling point


Why is the boiling point of octane so much higher than the boiling point of methane?

Because octane has more carbons, and the more carbons you have the higher the melting point. also octane is a gas that is very close to nonane (which is the first liquid) and that would mean it has a larger boiling point that methane (which is a gas that is the first one CH4). that is why octane has a larger boiling point that methane. Also, you can also figure it out the boiling points of each and look at the differences.


Why is the boiling point of methane higher than neon?

The intermolecular forces in neon are weaker than those in methane


Why is the boiling point of methane higher than propane?

The boiling point of methane is NOT higher, but lower than of propane (about 119 degrees lower), as can be seen from the table below:Methane: Bp. −161 °C, 112 KPropane: Bp. -42.1, 231.1 K


Why is the boiling point of ammonia lower than that of water?

because the ammonia has been filtered through the cat's kidneys removing all the properties within the ammonia that would make the boiling point higher than water


Why the boiling point of butane is higher than boiling point of methane?

Both compounds are straight chained alkanes. (General formula CnH2n-2) The general rule is the bigger the molecule in a group of similar compounds the higher boiling point it has. Methane is C1, butane is C4 - much bigger.


What is boiling point of methane?

The boiling point of methane is -161 degrees Celsius or -278.5 degrees Fahrenheit


What is the boiling point of ammonia?

The boiling point of ammonia is −33.34 °C (which is 240 K or -28 °F).


Why does methane have a boiling point?

Methane is gas derived from liquid methane.


Why is the boiling point of methane higher than the boiling point of ethane?

This is because methane is more stable or happier than ethane. It has a shorter carbon chain and less branching making it the harder one to boil.


What is the boiling point of ammonium?

The boiling point of ammonia at atmospheric pressure is -33.34oC.


Boiling points water and methane?

The boiling point of water is 100 0C at 760 mm col. Hg. The boiling point of methane is -164 0C.


Can methane be a gas at -161.5c as it's boiling point?

Indeed it can. At the boiling point liquid methane is in equilbrium with gaseous methane, so both exist simultaneously.


What is the meaning of melting point of ammonia and boiling point of ammonia?

The meaning is at what temperature does ammonia melt at and what temperature does ammonia boil at? for eg. waters melting point is 0 degrees celcius and the boiling point of water is 100 degrees celsius


Why hydrogen fluoride has higher boiling point than ammonia?

Because the hydrogen bonding in HF is much stronger than the intermolecular bonding in ammonia.


Which compound has a higher boiling point NF3 or NH3?

Ammonia: -33,34 0C Nitrogen trifluoride: -129 0C
