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.
No, oxygen and nitrogen do not form an ionic bond. They are both nonmetals and tend to form covalent bonds where they share electrons rather than transfer them.
Br2 is a covalent compound. It consists of two bromine atoms sharing electrons to form a covalent bond.
does aluminum and oxygen form a covalent bond
HCl gas is a covalent molecular compound, HCl in water dissociates to form H+(aq) + Cl-
Helium does not typically form bonds with other elements. It exists as a noble gas with a stable electron configuration, so it does not form ionic or covalent bonds.
no. they will form covalent bond
No it is not. Carbon is a covalent bond.
No, oxygen and nitrogen do not form an ionic bond. They are both nonmetals and tend to form covalent bonds where they share electrons rather than transfer them.
There is no electro negativity difference.The bond is covalent.

No. They form a covalent bond.
does aluminum and oxygen form a covalent bond
Covalent bond by sharing
Xe is an inert element that can't be combined in a chemical compound to form neither ionic or covalent bond.
Ionic, chlorine does not share any electrons with sodium to form a bond.
