Does N2 contains a polar covalent bond?
No. It contains non-polar covalent bond.
Which of the following molecules contains a covalent bond mgO hf hici cn-?
The molecule that contains a covalent bond is CN- (cyanide). MgO is an ionic compound, HF is a polar covalent molecule, and HCl is also a polar covalent molecule.
What has a molecules contains a polar covalent bond?
Water molecule contains a polar covalent bond. Oxygen attracts electrons more than hydrogen, creating a partial negative charge on the oxygen and a partial positive charge on the hydrogen atoms.
The bond that occurs because of the polar molecules of water is?
covalent bond
Can a compound be non-polar if it contains only 1 polar bond?
Not really. The closest thing would be molecules with long hydrocarbon chains such as decanal (C10H20O) with the C-O bond being polar. The carbon-hydrogen bonds are technically polar as well, but this polarity is very weak.
Which bond is strong covalent bond or ionic bond?
Ionic bonds are -generally speaking- stronger than single covalents.
What exists in all polar molecules?
A hydrogen bond
Do all polar molecules contain polar covalent bonds?
Yes, polar molecules contain polar covalent bonds. A polar covalent bond is formed when atoms with different electronegativities share electrons unevenly, creating a partial positive and partial negative charge. These charges result in an overall dipole moment for the molecule, making it polar.
What type of chemical bond must be present for must chemists to define molecules?
A covalent bond, (polar or non-polar)
Can CH2OH be miscible in water yet contain carbon?
There is no such compound as CH2OH. The compounds CH2O (formaldehyde) and CH3OH (methanol) do exist. Both contain carbon and are miscible in water for largely the same reason. Formaldehyde contains a highly polar C-O double bond while methanol contains both a polar C-O bond and a polar O-H bond. Polar bonds tend to make molecules water soluble.
What is a relatively weak bond between polar molecules?
A hydrogen bond is a relatively weak bond formed between polar molecules. It occurs between a hydrogen atom bonded to an electronegative atom (such as nitrogen, oxygen, or fluorine) and another electronegative atom in a different molecule.
Does a sugar molecule have a polar bond to a gasoline molecule?
No, a sugar molecule does not have a polar bond to a gasoline molecule. Sugar molecules mostly contain polar hydroxyl groups, while gasoline molecules are nonpolar hydrocarbons. Therefore, they do not form polar bonds with each other.
