Which is more polar FF or HF?
Among these F-F is least polar since both the F atoms have same electronegativity which means 0 difference in electronegativity between them. So the electronegativity difference between the two is very high and this makes H-F bond more polar.
Is methane polar or nonpolar Why?
Methane Does not have the charges present at the end because of finely distributed electrons and this distribution which is symmetrical cancel out each other. Hence it is non-polar.
Why is methane a polar molecule?
When a molecule is “symmetrical”, it means the dipoles cancel. All the outer atoms are the same – the same dipoles, and that the dipole moments are in the same direction – towards the carbon atom, the overall molecule becomes non-polar. Therefore, methane has non-polar bonds, and is non-polar overall.
Is methane a polar gas?
As we have seen, the C-H bonds in methane are polar. However, a molecule of methane is non-polar. Specifically, the dipole moment of methane is zero. A dipole moment of zero means that the “center of negative charge” in the molecule corresponds to the “center of positive charge”.
Which is more polar of or BF?
Among fluorine & iodine, the former is more electronegative. So, B−F bond is more polar.
Which bond is most polar FF?
Fluorine has highest electronegativity and iodine is least electronegative amongst group 17 elements so the electronegativity difference is highest in I−F. Hence it is most polar bond.
What kind of bond is methane?
covalent bonds
Methane has four covalent bonds between carbon (C) and hydrogen (H).
Why is ammonia polar?
NH3 is a polar molecule because, in the NH3 molecule, it has three dipoles because of three bonds and these dipoles do not cancel out each other. They form a net dipole moment. The three dipoles in one direction form a net dipole moment that determines the NH3 a polar molecule.
What is the Lewis structure of methane?

Is water more polar than methane?
Water is polar and can form intermolecular hydrogen bonds (due to high electronegativity of oxygen atom) Methane is non-polar and can only form weak dispersion forces between its molecules (carbon has a lower electronegativity)
What is the most polar molecule?
Water is the most polar molecule because a bond between oxygen and hydrogen has the most difference out of the atoms listed.
Which is more polar and why?
Oxygen is less electronegative than fluorine. Hence, oxygen in H2O attracts electron less towards itself from Hydrogen, as compared to Fluorine in HF. Hence, H2O is less polar than HF.
What’s the difference between methane and ethane in the atmosphere?
Both methane and ethane are colorless and odorless gaseous compounds at room temperature. Methane is a major greenhouse gas. Although ethane is also a greenhouse gas, it is less abundant in the atmosphere.
Which is more harmful to the environment propane or methane?
Both fuels produce a comparable amount of carbon dioxide, another greenhouse gas, when they are burned, although propane will release more carbon dioxide than methane. International Association for Natural Gas Vehicles: Emission Report, 2000. Glass Alchemy: Propane or Methane? Natural Handyman: Natural Gas Vs. Propane
How are ethane atoms bonded to each other?
The ethane molecule is composed of two carbon atoms bonded to each other via a single covalent bond. Each carbon atom is bonded to three hydrogen atoms. The geometry of ethane is given considering one carbon atom; it is tetrahedral at one carbon atom. Since there is a C-C sigma bond, the other sigma bonds are free to rotate around this C-C bond.
What happens when methane is mixed with carbon monoxide?
In the presence of insufficient air or oxygen, it partially burns into carbon monoxide (CO) gas. Substitution Reactions: Methane shows substitution reactions with halogens. In these reactions, one or more hydrogen atoms are replaced by an equal number of halogen atoms and it is called “halogenation.”
