The halogen Cl which is much more electronegative
When hydrogen and oxygen bind to form water, the electrons are shared between the hydrogen and oxygen atoms. This sharing creates a stable covalent bond in the water molecule.
The bond present in HCl is a polar covalent bond. This bond is formed by the sharing of electrons between the hydrogen atom and the chlorine atom, but the electrons are more strongly attracted toward the chlorine atom, giving it a partial negative charge and the hydrogen atom a partial positive charge.
Atoms can combine to achieve an octet of valence electrons by sharing electrons. The term covalent bond is used to describe the bonds in compounds that result from the sharing of one or more pairs of electrons.Ionic and covalent bonds differ in the extent to which a pair of electrons is shared by the atoms that form the bond. When one of the atoms is much better at drawing electrons toward itself than the other, the bond is ionic.When the atoms are approximately equal in their ability to draw electrons toward themselves, the atoms share the pair of electrons more or less equally, and the bond is covalent. This where sulfur dioxide fits in.
Yes. Water, or H2O, has covalent bonds.Related Information:Actually, they are polar covalent bonds. That means that the two hydrogen atoms form two covalent bonds with the one oxygen atom, causing it to be polar. This is because most of the electrons are pulled toward the hydrogen atoms, this will cause one end (Oxygen) of the molecule to be positively charged, and the other ends (Hydrogen) to be negatively charged. This is why water is known for it's hydrogen covalent bonds. That means that when one molecule of water is exposed to another molecule of water the negative ends of one are attracted to the positive end of the other (opposites attract). This polar attraction is what causes water have surface tension.
A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electrostatic force of attraction between opposite charges, either between electrons andnuclei, or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such as dipole--dipole interactions, the London dispersion force andhydrogen bonding.Since opposite charges attract via a simple electromagnetic force, the negatively charged electrons that are orbiting the nucleus and the positively charged protons in the nucleus attract each other. An electron positioned between two nuclei will be attracted to both of them, and the nuclei will be attracted toward electrons in this position. This attraction constitutes the chemical bond. The most stable configuration of nuclei and electrons is one in which the electrons spend more time betweennuclei, than anywhere else in space. Due to the matter wave nature of electrons and their smaller mass, they must occupy a much larger amount of volume compared with the nuclei, and this volume occupied by the electrons keeps the atomic nuclei relatively far apart, as compared with the size of the nuclei themselves. This phenomenon limits the distance between nuclei and atoms in a bond.Added:To simplify, a covalent bond exists between the hydrogens in water and the oxygen. Since oxygen is highly electronegative, compared to hydrogen, the covalent bonds are unequal and called polar covalent.
In a polar covalent bond, the electrons are pulled more toward certain elements, giving them a partial charge. In a non polar bond, the electrons are evenly or close to evenly shared.

Covalent compounds share electrons when bonding. Because the bond is shared it is weaker than an ionic bond which transfers electrons. The bond is being pulled in two different directions toward each nonmetal, hence, it is more easily broken.

This is a Polar covalent bond, where because if the atom in the bond are electronegatively different, the electron mass is polarized toward the more electronegative.

Polar molecules have one end that is more negative(it has the electrons more of the time) and one end that is positive(it has the electrons less of the time) In other words the electrons that are shared in the covalent bond are not shared evenly. Therefore, it can attract other things that are polar. Non polar molecules share evenly and do not have a partial charge so do not attract things that have charges. .
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.
