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.
Both of these compounds are alkanes.
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 is not polar.So it is in soluble in polar compounds
Ch4 is not an element, it's the compound Methane
CH4

Methane (CH4) is a gas; the boiling point is at -164 0C.
Both of these compounds are alkanes.
Graphite by a long way
NaCl
Look at intermolecular forces and judge from there

Electron group arrangment and molecular geometry is same.It is tetrahedral in shape
200 g CH4 x 1 mole CH4/16 g = 12.5 moles CH4
Methane is CH4
the CH4 poler
