What molecule has the highest boiling point methane chloromethane or methanol?
methanol
Why is methane insoluble but methanol is soluble?
Generally speaking 'like dissolves like' so when you thinking if a molecule can dissolve in a particular solvent, you need to decide what type of bonding that solvent can exhibit and what bonding the molecule in question exhibits. So for example water can exhibit hydrogen bonding. This means for something to be able soluble in water, it too needs to be able to exhibit hydrogen bonding. Methane only contains hydrogen and carbon and thus, will not exhibit hydrogen bonding. However, methanol has carbon, hydrogen and oxygen and therefore, can exhibit hydrogen bonding. As a result, using the 'like dissolve like' approach we can see why methane will be insoluble in water but methanol will be soluble.
Is methanol more soluable than methane?
Yes, methanol is CH3OH and methane is CH4. Methanol is polar (because of the O-H bond) and methane is non-polar (because it is a hydrocarbon.) Water (which is polar) will dissolve other polar things, but not non-polar things.
Why are methanol and higher hydrocarbons easier and cheaper to transport than methane?
they are liquids
Boiling points water and methane?
Water boils at a higher temperature than methane because water is a polar compound. Each molecule is held together chemically. Each molecule is held to other molecules by hydrogen bonding. With Methane, it is every molecule for itself.
What molecule has the highest boiling point methane chloromethane or methanol?
methanol
Why methane mercaptan has a lower boiling point than methanol even though methyl mercaptan has a higher molecular weight?
For the same reason that water isn't a gas. Oxygen is highly electronegative and the hydrogen bonding present in water and methanol raises the intermolecular attractive forces and results in a higher boiling point.
Does methanol have a greater density than methane?
yes, it has to because it has an OH group which participates in hydrogen bonding. this is why it stays in liquid phase at lower temperatures than methane.

Why is methanol a hydrocarbon?
because methane is a hydrocarbon!
Why is the enthalpy change of combustion for methanol less negative than methane?
The combustion of methanol to form products of H2O and CO2 do not have as much of an energy change compared to methane and a result methanol releases less energy compared to methane. The more negative an enthalpy change is, the more heat it is going to release.
Does water or methane have a stronger force of attraction between its particles?
Water is a polar molecule whereas methane is a non-polar molecule.The intra- molecular force in water molecule is much stronger compared top the intra- molecular force between a carbon and a hydrogen in methane.Water molecule have hydrogen bonding as its intra molecular force.Hydrogen bonding is the strongest, then comes dipole-dipole and the least strong is the London dispersion force.The molecular bonding of water is higher than that of methane (binding energy), and the intermolecular bonding of water is higher than that of methane (boiling point).
Why is the boiling point of methane much lower than the boiling point of hydrochloric acid?
Because of the hydrogen bonds in HCl and it's polarity. High polarity = high boiling point. All alkanes (methane) are nonpolar and have low boiling points. Alcohols and compounds with hydrogen bonding have higher boiling points because hydrogen bonds are very strong. Ask a chemistry teacher if you need a better explanation.
Difference between methanol and ethanol?
Methanol is CH3OH, ethanol is CH3CH2OH. Both are alcohols, ethanol has one carbon more (or a CH2 group more) and is less polar than methanol. Also ethanol has higher boiling point than methanol.
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.
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 bond type is methane?
covalent bonding
