Does methanol form a covalent or ionic bond?

Answer 1

yes because in the molecule CH3OH, oxygen has a very high electronegativity (tendency to atract electrons toward its nucleus) and as such, it pulls the electrons of the sigma-bonds with carbon and hydrogen, toward itself and takes on a partial negative charge. The carbon and especially the OH hydrogen have partial loss of electrons in the bond, and thus assume a partial positive charge. In solution, the negative oxygen centers attract the positive hydrogen centers and form what is known as hydrogen bonding, an electrostatic attraction between oxygen (-) and hydrogen (+). The molecule has an unequal distribution of +/- charge on its surface, and thus is deemed polar. Contrast this with methane (CH4) which is non-polar for symmetrical geometric reasons as well as electronagtivity reasons.

Answer 2

Methanol is considered a polar solvent. The structure of methanol is a hydroxyl group (-OH) attached to a methane (-CH3). The hydroxyl has a greater negative charge than the methane, resulting in an effective polarity of the solvent.

Answer 3

Methane is a symmetrical molecule with a central carbon atom with 4 hydrogen atoms about it that forms a tetrahedron. Each of the bonds are slightly polar, but overall, it's a non-polar molecule.

Answer 4

both bonds have electrical conductivity in water solutions, both have form chemical bonds, they both have melting points and solubility. ~Josh~

Answer 5

Methanol is covalent because it only contains NONmetal elements. An ionic bond needs a metal element.

Answer 6

Yes, methanol is covalent as are all alcohols.

Answer 7

No, Methanol is polar, but Hydrogen bond is not there

Answer 8

Methanol, CH3OH is a covalent molecule

Answer 9

Methanol has covalent bonds.

Answer 10

It forms a covalent bonding
