NaCl
The boiling point in degree Celsius are given below:Na: 883K: 774Si: 2355Ne: -246Silicon has the highest boiling point among the elements given.
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.
Methane (CH4) is a gas; the boiling point is at -164 0C.
Graphite has a higher boiling point than CH4. Graphite is a form of carbon arranged in layers, held together by strong covalent bonds, resulting in a higher boiling point. CH4 (methane) is a simple gas composed of one carbon and four hydrogen atoms, with weaker intermolecular forces leading to a lower boiling point.
The order from lowest to highest melting point is: CH4, NH3, H2S, Na2O, He.

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.

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
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.
CH4 (methane) is the compound that contains carbon. Calcium (Ca) and sodium chloride (NaCl) do not contain carbon.

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.
