∙ 9y agoChloromethane is actually a polar molecule except for the case of tetrachloromethane. This is because the polar C-Cl bond is canceled out by the tetrahedral symmetry.

∙ 10y agoThe chlorine atom withdraws the electron pair of C-Cl bond which creates a net dipole moment in the same direction.

∙ 11y agoNo, methanol is more polar due to high electronegativity of oxygen and attachments of a carbon and a hydrogen atom to the oxygen atom.

Which chemical bond in the molecule of chloromethane is more polar the carbon-chlorine or carbon-hydrogen bond?
The chemical bond between carbon-chlorine has an electronegativity difference of 0.61. The bond between carbon-hydrogen has a difference of 0.35, thus is less polar than the carbon-chlorine bond.
Why is methanol more polar than ethanol?
Methane is CH4 or H-CH3 Ethane is CH3-CH3 When compared to H- (in methane), the CH3- (methyl group in ethane) is more electron donating and hence ethane is more basic than methane.
Is ammonia mlecule NH3 more polar than water molecule?
no, water is more polar than ammonia.
Is ethyl acetate more polar than toluene?
Yes, ethyl acetate is more polar than toluene.
Does ethanol burn more cleanly than methane?
no. lol
Why is the boiling point of methane higher than neon?
Chloromethane has a permanent dipole because of the chlorine molecule attached to the carbon, which means the chlorine has a partial negative charge while the carbon has a partial positive charge. These charges allow certain molecules of chloromethane to be "attracted" to other chloromethane molecules' oppositely charged regions (dipole-dipole interactions). These attractive intermolecular forces hold the molecules together and need to be broken in order for chloromethane to reach its boiling point, which requires a greater input of energy (heat). In comparison, ethane only has the weakest intermolecular interactions holding the molecules together (van der Waals attractive forces / London forces). London forces are weak compared to dipole-dipole interactions and so less energy (heat) is required to break the bonds. The result is that chloromethane has a higher boiling point than ethane because more heat is required to break the intermolecular bonds between chloromethane than is required to break the bonds between ethane.
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 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.
What compound is more polar and soluble in water methane or methanol and why?
Acetonitrile is slightly more polar than methanol. This is due to the presence of the C-N triple bond in acetonitrile (CH3CN).
Why is methanol more polar than ethanol?
Methane is CH4 or H-CH3 Ethane is CH3-CH3 When compared to H- (in methane), the CH3- (methyl group in ethane) is more electron donating and hence ethane is more basic than methane.
Does methane float on water?
No. methane is not soluble in water, as methane is a non-polar hydrocarbon and water is a polar solvent.
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.
Is toluene more polar than Chloroform?
yes toluence is more polar than chloroform
Is methane a covalent compound?
Yes, CH4 is "methane" A covalent compound is a compound in which the atoms that are bonded share electrons rather than transfer electrons from one to the other. Ammonia and water are also Covalent. http://misterguch.brinkster.net/covalentcompounds.html
Is ammonia mlecule NH3 more polar than water molecule?
no, water is more polar than ammonia.
Why H2O is more polar than H2S?
Oxygen is more electronegative than sulfur, resulting in more polar bonds with hydrogen.
